Subject: dma: timb_dma: remove unnecessary platform_set_drvdata()
X-Git-Tag: upstream/snapshot3+hdmi~4764^2~27
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c1a9d391adc7feb219edd354deacb587b26cad06;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

dma: timb_dma: 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.
