Subject: misc: ep93xx_pwm: remove unnecessary platform_set_drvdata()
X-Git-Tag: next-20130521~22^2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e7d87ca1089165c05376df50f1be0f68d72ab08b;p=karo-tx-linux.git

misc: ep93xx_pwm: 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.
