When this driver was upgraded to the vendor
20100831 version in
commit
93c55dda092c7 et al,, one listhead initialization was missed.
This broke complete operation of the driver whenever AP mode was
enabled. This fixes https://bugs.archlinux.org/task/27996.
The configuration parameter R8712_AP is misleading as the driver cannot
function as an AP without a heavily hacked version of hostapd. Thus, it
makes sense to remove the parameter; however the code and data configured
for the option is left in.

staging:iio:adc:adt7310/7410 sticking plaster fix for broken event attrs.
Neither of these drivers has ever been anywhere near the iio abi.
Probably as a result of this the fact they had two event groups
each was not picked up when we restricted IIO to having only
1 event line per device (as part of the chrdev merge set).
As such these definitely didn't work before. This patch squishes
the only element from the 'comparator' event line that isn't in the
'interrupt' one into it and kills off the 'comparator' one.
Ultimately both of these drivers belong in hwmon not IIO and are just
waiting here because I don't want to kill off a driver that may
prove useful to someone. (Ultimately I will ask Greg to scrap
these two if no one steps up to deal with them.)

Advantech PCI-1739U support
Hello,
I've added a bit of simple configuration to adv_pci_dio.c in order to
make the PCI-1739U work with the adv_pci_dio driver. I have tested
inputs only so far but they seem to work. A git style patch is
attached.
Thanks,

However, from the device's point of view, there is just a single
capture and playback stream, which must be shared between these
subsystems. It is therefore necessary to maintain the state of the
subsystems with respect to PCM usage. We define several constants of
the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
following meanings:
*) <subsystem> is one of
-) ALSA: PCM playback and capture via ALSA
-) MONITOR: software monitoring
-) IMPULSE: optional impulse response measurement
*) <direction> is one of
-) PLAYBACK: audio output (from host to device)
-) CAPTURE: audio input (from device to host)
*) <resource> is one of
-) BUFFER: buffer required by PCM data stream
-) STREAM: actual PCM data stream
The subsystems call line6_pcm_acquire() to acquire the (shared)
resources needed for a particular operation (e.g., allocate the buffer
for ALSA playback or start the capture stream for software monitoring).
When a resource is no longer needed, it is released by calling
line6_pcm_release(). Buffer allocation and stream startup are handled
separately to allow the ALSA kernel driver to perform them at
appropriate places (since the callback which starts a PCM stream is not
allowed to sleep).

staging: precedence bug in crystalhd_stop_tx_dma_engine()
The intent here is to see if we have cleared the DMA_START_BIT flag. We
clear it a couple lines later. The current code has a precedence bug so
it is equivalent to "if (!dma_cntrl) { ...".

staging: r8712u: Simplify semaphores
I am preparing to convert this driver from semaphore to mutex locking,
The first step has been to eliminate a number of semaphores that were
initialized but never used, and one whose only use was a single "up"
after initialization. A total of 9 semaphores were removed in this process.
One other change was to remove some inline semaphore routines that were
unused.
In addition, several cases had the following structure:
down()
if () {
...
}
up()
The locking overhead was reduced by moving the up/down inside the if
block.
