Merge tag 'iio-for-3.17b' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Second round of new drivers and cleanups for IIO in the 3.17 cycle.

New drivers
* mcp4902, mcp4912 and mcp4922 SPI DAC driver.
* max1027, max1029 and max1031 SPI ADC driver.

Cleanups
* cm32181 - use devm APIs to simplify error paths.
* ak8975 - use devm APIs to simplify error paths.
* ad9850 - drop some unused defines and an unnecessary goto.
* hmc5843 - add missing devices to the device id table and the documentation.
* ad9832 - small formatting cleanups.
* sca3000 - hide direct use of the stufftoread element by adding a
data_available function. This is a precursor for the addition of buffer
watermarks to the subsystem but stands as a good cleanup on its own.

staging/lustre/ptlrpc: Add schedule point to ptlrpc_check_set()

Most ptlrpc sets are believed to be small and bounded in length.  However
at the very least the ptlrpcd reuses the ptlrpc sets at its primary work
queue.  This work queue can easily have work added faster than the ptlrpcd
thread can process the work.  The unbounded work can lead to the ptlrpcd
monopolizing a CPU for hundreds of seconds.  Obviously a well-behaved
kernel function should obey the scheduler and share the processor.

We address that problem by inserting a cond_resched() at the top of the
main loop of ptlrpc_check_set().

Some have suggested putting the cond_resched() lower in the loop.  However,
the only current way to bound the number of loops that we exceed our
allocated run time is to put the call at the top of the loop.  Putting it
lower would allow an unknown number (and since it is unknown, it might be
excessively large at times) of cycles through the loop before a
resched is allowed.

staging/lustre/mgc: replace hard-coded MGC_ENQUEUE_LIMIT value

During client mount, the client will send an LDLM_ENQUEUE request to
MGS with send delay set to MGC_ENQUEUE_LIMIT, which is hard coded to
50 seconds. On the other hand, the interval for pinger is deduced from
obd_timeout. When obd_timeout is configured for a longer period of
time, so does the pinger. We know that connecting to the secondary MGS
node is triggered by the pinger. Now that we have a longer interval,
the pinger will not be able to try the secondary before the
LDLM_ENQUEUE request fails the mount using the same delay limit.

This code change will replace the hard-coded send delay being
mentioned above with a value that is long enough to give the client a
chance to connect to the secondary MGS if exists.

staging/lustre/libcfs: revert changes to libcfs_sock_ioctl

Changes introduced by 80db2734acbc78db12798cfb611d6acc7fe389e6
unfortunately totally break lustre, we use this function
to access not only socket proto obs, but also device ioctl
like SIOCGIFCONF that now fail.
Reverting part of the previous patch to regain the needed
functionality.
