  Revert "Staging: olpc_dcon: Remove obsolete driver" (2016-04-04 13:52:35 
-0700)


Staging / IIO driver fixes for 4.6-rc3

Here are some IIO driver fixes, along with two staging driver fixes for
4.6-rc3.

One staging driver patch reverts the deletion of a driver that happened
in 4.6-rc1.  We thought that laptop.org was dead, but it's still alive
and kicking, and has users that were mad we broke their hardware by
deleting a driver for their machines.  So that driver is added back and
everyone is happy again.

All of these have been in linux-next for a while with no reported issues.

[PATCH] staging: fsl-mc: get rid of mutex_locked variables

2016-04-09 Thread Cihangir Akturk

Remove mutex_locked variables which are used to determine whether mutex is
locked, instead add another label to unlock mutex on premature exits due to
an error.

This patch also addresses the folowing warnings reported by coccinelle:

drivers/staging/fsl-mc/bus/mc-allocator.c:237:1-7: preceding lock on line 204
drivers/staging/fsl-mc/bus/mc-allocator.c:89:1-7: preceding lock on line 57

[PATCH] staging: lustre: split error handling code into multiple labels

2016-04-09 Thread Cihangir Akturk

Instead of using a switch-case statement to find out what kind of error
has just happened, split error handling logic into multiple labels and
jump right into the appropriate label to do the error handling. This way
it is easier to follow different code paths. It also looks easy on the
eyes.

Additionally silences the following coccinelle warning:

drivers/staging/lustre/lustre/obdecho/echo_client.c:762:22-27: ERROR: ed
is NULL but dereferenced.
