Subject: rx51_battery: Remove unnecessary platform_set_drvdata()
X-Git-Tag: firefly_0821_release~176^2~5739^2~18
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f70d739ada3298fd613d738c0a1c8b10cef63bdf;p=firefly-linux-kernel-4.4.55.git

rx51_battery: Remove unnecessary platform_set_drvdata()

The driver core clears the driver data to NULL after device_release or on
probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is
not needed to manually clear the device driver data to NULL.
