Subject: drivers/block/swim.c: remove unnecessary platform_set_drvdata()
X-Git-Tag: firefly_0821_release~176^2~5340^2~271
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c07303c0af38ffb1e5fd9b5ff37d0798298a7acf;p=firefly-linux-kernel-4.4.55.git

drivers/block/swim.c: remove unnecessary platform_set_drvdata()

The driver core clears the driver data to NULL after device_release or
on probe failure.  Thus, it is not needed to manually clear the device
driver data to NULL.
