ALC269 codec has a few different variants, and each of them may have
different ADC and MUX widgets. For example, one model has ADC 0x08
with MUX 0x23 while others has ADC 0x09 or ADC 0x07 with MUX 022 or
0x24. The difference of ADC appears usually as the capability of
the digital mic pin (0x12), and the current driver sometimes misses
the internal mic pin due to the mismatching ADC.
This patch adds a bit more clever way to find the matching ADC instead
of the static list. Now the driver checks all active input pins and
fills only the ADC/MUX's that contain all of them.

a device is removed from that hub, it's likely that a kernel panic follows.

USB: Fix usb_fill_int_urb for SuperSpeed devices
USB 3 and Wireless USB specify a logarithmic encoding of the endpoint
interval that matches the USB 2 specification. usb_fill_int_urb() didn't
know that and was filling in the interval as if it was USB 1.1. Fix
usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case
alone, because David Vrabel wants to keep the old encoding.
Update the struct urb kernel doc to note that SuperSpeed URBs must have
urb->interval specified in microframes.
Add a missing break statement in the usb_submit_urb() interrupt URB
checking, since wireless USB and SuperSpeed USB encode urb->interval
differently. This allows xHCI roothubs to actually register with khubd.

Fix it by replacing min() with min_t() in tty_insert_flip_string_flags and
tty_insert_flip_string_fixed_flag().

hvc_console: Fix race between hvc_close and hvc_remove
Alan pointed out a race in the code where hvc_remove is invoked. The
recent virtio_console work is the first user of hvc_remove().
Alan describes it thus:
The hvc_console assumes that a close and remove call can't occur at the
same time.
In addition tty_hangup(tty) is problematic as tty_hangup is asynchronous
itself....
So this can happen
hvc_close hvc_remove
hung up ? - no
lock
tty = hp->tty
unlock
lock
hp->tty = NULL
unlock
notify del
kref_put the hvc struct
close completes
tty is destroyed
tty_hangup dead tty
tty->ops will be NULL
NULL->...
This patch adds some tty krefs and also converts to using tty_vhangup().

uartlite: Fix build on sparc.
We can get this driver enabled via MFD_TIMBERDALE which only
requires GPIO to be on.
But the of_address_to_resource() function is only present on
powerpc and microblaze, so we have to conditionalize the
CONFIG_OF probing bits on that.

tty: Take a 256 byte padding into account when buffering below sub-page units
The TTY layer takes some care to ensure that only sub-page allocations
are made with interrupts disabled. It does this by setting a goal of
"TTY_BUFFER_PAGE" to allocate. Unfortunately, while TTY_BUFFER_PAGE takes the
size of tty_buffer into account, it fails to account that tty_buffer_find()
rounds the buffer size out to the next 256 byte boundary before adding on
the size of the tty_buffer.
This patch adjusts the TTY_BUFFER_PAGE calculation to take into account the
size of the tty_buffer and the padding. Once applied, tty_buffer_alloc()
should not require high-order allocations.

Revert "tty: Add a new VT mode which is like VT_PROCESS but doesn't require a VT_RELDISP ioctl call"
This reverts commit
eec9fe7d1ab4a0dfac4cb43047a7657fffd0002f.
Ari writes as the reason this should be reverted:
The problems with this patch include:
1. There's at least one subtlety I overlooked - switching
between X servers (i.e. from one X VT to another) still requires
the cooperation of both X servers. I was assuming that KMS
eliminated this.
2. It hasn't been tested at all (no X server patch exists which
uses the new mode).
As he was the original author of the patch, I'll revert it.

node_read_distance() has a BUILD_BUG_ON() to prevent buffer overruns when

Each node only needs four chars: three for distance (maximum distance is
