From: Jingoo Han Date: Mon, 6 May 2013 03:53:33 +0000 (+0900) Subject: dma: at_hdmac: remove unnecessary platform_set_drvdata() X-Git-Tag: next-20130617~70^2~2^2~5 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ce5c02a4d2d675b20ed4346fa301a015ffab203e;p=karo-tx-linux.git dma: at_hdmac: 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.
