media: Add MIPI CCI register access helper functions
The CSI2 specification specifies a standard method to access camera sensor
registers called "Camera Control Interface (CCI)".
This uses either 8 or 16 bit (big-endian wire order) register addresses
and supports 8, 16, 24 or 32 bit (big-endian wire order) register widths.
Currently a lot of Linux camera sensor drivers all have their own custom
helpers for this, often copy and pasted from other drivers.
Add a set of generic helpers for this so that all sensor drivers can
switch to a single common implementation.
These helpers take an extra optional "int *err" function parameter,
this can be used to chain a bunch of register accesses together with
only a single error check at the end, rather than needing to error
check each individual register access. The first failing call will
set the contents of err to a non 0 value and all other calls will
then become no-ops.

Reserved memory can be either looked up using the generic function
of_address_to_resource() or using the special of_reserved_mem_lookup().
The latter has the advantage that it ensures that the referenced memory
region was really reserved and is not e.g. status = "disabled".
of_reserved_mem also supports allocating reserved memory dynamically at
boot time. This works only when using of_reserved_mem_lookup() since
there won't be a fixed address in the device tree.

media: atomisp: Fix smatch warnings caused by atomisp custom assert() usage
The atomisp code base has a custom assert() macro, a couple of functions
use this in a construction like the following:
assert(pipe);
assert(pipe->stream);
if ((!pipe) || (!pipe->stream)) {
ia_css_debug_dtrace(IA_CSS_DEBUG_TRACE_PRIVATE,
"allocate_mipi_frames(%p) exit: ...\n",
pipe);
return -EINVAL;
}
The second assert is seen by smatch as dereferencing "pipe" in the above
example (and dereferencing "dvs_6axis_config" in the other case).
Following by the dereferenced variable being checked (a second time)
in the following if () statement.
This triggers the following smatch warnings:
drivers/staging/media/atomisp/pci/sh_css_mipi.c:356 allocate_mipi_frames() warn: variable dereferenced before check 'pipe' (see line 355)
drivers/staging/media/atomisp/pci/sh_css_mipi.c:562 send_mipi_frames() warn: variable dereferenced before check 'pipe' (see line 561)
drivers/staging/media/atomisp/pci/sh_css_param_dvs.c:208 free_dvs_6axis_table() warn: variable dereferenced before check 'dvs_6axis_config' (see line 206)
The custom assert() macro actually expands to a BUG() call and BUG()
calls should not be used in the kernel.
Remove the assert() calls to fix the smatch warnings and in case of
[allocate|send]_mipi_frames() also remove the if () return -EINVAL
block since these functions are never called with a NULL pipe.

media: ipu3-cio2: allow ipu_bridge to be a module again
This code was previously part of the VIDEO_IPU3_CIO2 driver, which could
be built-in or a loadable module, but after the move it turned into a
builtin-only driver. This fails to link when the I2C subsystem is a
module:
x86_64-linux-ld: drivers/media/pci/intel/ipu-bridge.o: in function `ipu_bridge_unregister_sensors':
ipu-bridge.c:(.text+0x50): undefined reference to `i2c_unregister_device'

ipu-bridge.c:(.text+0x9c9): undefined reference to `i2c_acpi_new_device_by_fwnode'
In general, drivers should not have to be built-in, so change the option
to a tristate with the corresponding dependency. This in turn opens a
new problem with the dependency, as the IPU bridge can be a loadable module
while the ipu3 driver itself is built-in, producing a new link failure:
86_64-linux-ld: drivers/media/pci/intel/ipu3/ipu3-cio2.o: in function `cio2_pci_probe':
ipu3-cio2.c:(.text+0x197e): undefined reference to `ipu_bridge_init'
In order to fix this, restore the old Kconfig option that controlled
the ipu bridge driver before it was split out, but make it select a
hidden symbol that now corresponds to the bridge driver.
When other drivers get added that share ipu-bridge, this should cover
all corner cases, and allow any combination of them to be built-in
or modular.

media: cec: core: add adap_nb_transmit_canceled() callback
A potential deadlock was found by Zheng Zhang with a local syzkaller
instance.
The problem is that when a non-blocking CEC transmit is canceled by calling
cec_data_cancel, that in turn can call the high-level received() driver
callback, which can call cec_transmit_msg() to transmit a new message.
The cec_data_cancel() function is called with the adap->lock mutex held,
and cec_transmit_msg() tries to take that same lock.
The root cause is that the received() callback can either be used to pass
on a received message (and then adap->lock is not held), or to report a
canceled transmit (and then adap->lock is held).
This is confusing, so create a new low-level adap_nb_transmit_canceled
callback that reports back that a non-blocking transmit was canceled.
And the received() callback is only called when a message is received,
as was the case before commit
f9d0ecbf56f4 ("media: cec: correctly pass
