X-Git-Tag: upstream/snapshot3+hdmi~4788^2~173
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7b32b631fb30ef3982d1bdcbb9242873029b46aa;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

rtc: rtc-ep93xx: remove unnecessary platform_set_drvdata()

The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
= NULL when no driver is bound").  Thus, it is not needed to manually
clear the device driver data to NULL.
