Subject: [PATCH 2/2] dma: timb_dma: remove unnecessary platform_set_drvdata()
Date: Mon, 06 May 2013 12:54:48 +0900 [thread overview]
Message-ID: <002801ce4a0d$744ff330$5cefd990$@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.
