Subject: [PATCH 2/2] misc: ep93xx_pwm: remove unnecessary platform_set_drvdata()
Date: Tue, 07 May 2013 14:34:15 +0900	[thread overview]
Message-ID: <003801ce4ae4$830d02f0$892708d0$@samsung.com> (raw)

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.
