Fix that by explicitly masking all interrupts before setting the interrupt

media: omap3isp: Use struct_group() for memcpy() region

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields. Wrap the target region
in struct_group(). This additionally fixes a theoretical misalignment
of the copy (since the size of "buf" changes between 64-bit and 32-bit,
but this is likely never built for 64-bit).

FWIW, I think this code is totally broken on 64-bit (which appears to
not be a "real" build configuration): it would either always fail (with
an uninitialized data->buf_size) or would cause corruption in userspace
due to the copy_to_user() in the call path against an uninitialized
data->buf value:

omap3isp_stat_request_statistics_time32(...)
    struct omap3isp_stat_data data64;
    ...
    omap3isp_stat_request_statistics(stat, &data64);

int omap3isp_stat_request_statistics(struct ispstat *stat,
                                     struct omap3isp_stat_data *data)
    ...
    buf = isp_stat_buf_get(stat, data);

static struct ispstat_buffer *isp_stat_buf_get(struct ispstat *stat,
                                               struct omap3isp_stat_data *data)
...
    if (buf->buf_size > data->buf_size) {
            ...
            return ERR_PTR(-EINVAL);
    }
    ...
    rval = copy_to_user(data->buf,
                        buf->virt_addr,
                        buf->buf_size);

Regardless, additionally initialize data64 to be zero-filled to avoid
undefined behavior.

media: mexon-ge2d: fixup frames size in registers

The CLIP, SRC & DST registers are coded to take the pixel/line start & end,
starting from 0. Thus the end should be the width/height minus 1.

It can be an issue with clipping and rotation, where it will add spurious
lines from uninitialized or unwanted data with a shift in the result.

[  140.231038] atomisp-isp2 0000:00:03.0: hmm_init Failed to create sysfs

The problem is that dummy_ptr == 0 is a valid value. So, change the logic
which checks if dummy_ptr was allocated.

At this point, atomisp now gives WARN_ON() in hmm_free() [2] on atomisp
reload by rmmod/insmod. Again, the check is wrong there.

So, change both checks for mmgr_EXCEPTION, which is the error value when
HMM allocation fails, and initialize dummy_ptr with such value.

The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on
after having turned it off causes the CPLM3218 ambient-light-sensor on
the front camera sensor's I2C bus to crash, hanging the bus.

Add a DMI quirk table for systems on which to leave eldo2 on.

Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor
as long as the camera sensor is being used, this is what Windows seems
to do as a workaround (based on analyzing the DSDT). But that is not
easy to do cleanly under Linux.

media: atomisp_gmin_platform: Add enable-count to gmin_[v1p8|v2p8]_ctrl()

On devices with 2 sensors the 2 sensors may get probed simultaneously
and the v1p8 and v2p8 regulators are ususally shared between the
2 sensors.

This means that the probe() function of sensor 1 may end up calling
gmin_v1p8_ctrl(..., false) turning the regulator off while sensor 2's
probe() function still needs it to be on, causing the probe() of
sensor 2 to sometimes fail.

Fix this by adding an enable-count for both regulators and only
disabling them again when that goes to 0.

Note all this really should be converted to use the standard kernel
regulator framework, I have doing this on my long term TODO list,
this fix is only meant as a temporary workaround for the issue.

V4L2_CAP_TIMEPERFRAME via .vidioc_s_parm() operation should also
support .vidioc_enum_frameintervals().  If the former is implemented

operation is not supported by the subdevice and failure is returned by
the video device, the compliance test issues a warning.

Implement the missing pad operation.  Enumerate frame intervals

.s_frame_interval(), but not exceeding a reasonable maximum of 1

path, so only frame scaling is applied as needed and crop rectangle is

media: ov6650: Add try support to selection API operations

Try requests are now only supported by format processing pad operations
implemented by the driver.  The driver selection API operations
currently respond to them with -EINVAL.  While that is correct, it
constraints video device drivers to not use subdevice cropping at all
while processing user requested active frame size, otherwise their set
try format results might differ from active.  As a consequence, we
can't fix set format pad operation as not to touch crop rectangle since
that would affect users not being able to set arbitrary frame sizes.
Moreover, without a working set try selection support we are not able
to use pad config crop rectangle as a reference while processing set
try format requests.

Implement missing try selection support.  Moreover, as it will be now
possible to maintain the pad config crop rectangle via selection API,
start using it instead of the active one as a reference while
processing set try format requests.

is_unscaled_ok() helper, now also called from set selection operation,
has been just moved up in the source file to avoid a prototype, with no

media: ov6650: Fix set format try processing path

According to subdevice interface specification found in V4L2 API
documentation, set format pad operations should not affect image
geometry set in preceding image processing steps. Unfortunately, that
requirement is not respected by the driver implementation of set format
as it was not the case when that code was still implementing a pair of
now obsolete .s_mbus_fmt() / .try_mbus_fmt() video operations before
they have been merged and reused as an implementation of .set_fmt() pad
operation by commit 717fd5b4907a ("[media] v4l2: replace try_mbus_fmt
by set_fmt").

In case of set format active processing path the issue can be fixed
easily by excluding a call to set active selection from that path. That
will effectively limit frame size processing to optimal frame scaling
against active crop rectangle without touching it.  Users can just call
set active selection themselves to obtain desired frame size.  However,
set format try processing path needs more work.

First of all, the driver should be extended with set try selection
support.  Lack of it constraints video device drivers to not use
subdevice cropping at all while processing user requested active frame
size, otherwise their set try format results might differ from active.

Next, set format try processing path should use pad config crop
rectangle as a reference, not the active one as it does now.  That
issue can be resolved easily as soon as set try selection support is
added to the driver so pad config crop rectangle can be maintained by
users via selection API.

Last, set format try processing path should give the same results as
active in respect to active vs. pad config crop rectangle geometry.
Both rectangles should be either not touched by set format (that's what
we are going to achieve) or modified the same way, otherwise users
won't be able to obtain equal results from both paths while iterating
through set format and set selection operations in order to obtain
desired frame size.

We can't begin with modifying set format pad operation as not to touch
crop rectangle since that depends on availability of set try selection
for symmetry.  Neither can we begin with adding set try selection since
that in turn depends on equal handling of active and pad config crop
rectangles by set format.  We can either implement all required
modifications in a single patch, or begin with fixing current set
format try processing path to appropriately handle pad config crop
rectangle.  This patch implements the latter approach as believed to
be more readable.

Move crop rectangle adjustments code from a helper (the former
implementation of .s_fmt(), now called from set format active
processing path) to the body of set format pad operation function
where it can be also used for processing try requests for symmetry with
active ones.  As the helper no longer processes frame geometry, only
frame format and half scaling, simplify its API accordingly and update
its users.

Moreover, extract code that applies crop rectangle hardware limits
(now a part of .set_selection() operation which is called from set
format active processing path) to a new helper and call that helper
from set format try processing path as well for symmetry with active.
