Date: Tue, 24 May 2016 12:15:25 -0700 From: Alison Schofield <amsfield22@...il.com> To: jic23@...nel.org Cc: lars@...afoo.de, Michael.Hennerich@...log.com, knaack.h@....de, pmeerw@...erw.net, linux-iio@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 0/7] iio: adc: clean up claims on direct mode in ad7* drivers This set looks at the ad7* drivers and migrates them to use the iio helper functions iio_device_claim|release_direct_mode(). The first three (7266,7791,7793) were not already holding a lock on direct mode, so this will be a change in behavior for those drivers. The last four (7476,7887,7923,799x) were already locking so these are migrations to the claim/release helper functions. Worth noting: This does not clean up all mlock (ab-)uses in ad799x. This driver is still using mlock in a few other places not associated with locking down direct mode.
