Subject: driver core: dev_set_drvdata returns void
X-Git-Tag: firefly_0821_release~176^2~3465^2~40^2~7
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2c1f1ff0f0d9e0df8c9b6d3697ac250900091541;p=firefly-linux-kernel-4.4.55.git

driver core: dev_set_drvdata returns void

dev_set_drvdata can no longer fail, so it could return void.

All callers have hopefully been updated to no longer check for the
return value.
