Subject: mtd: nand: jz4740_nand: remove unnecessary platform_set_drvdata()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1b03147277e38ef0cbe0f92bc2b908c7419b55ea;p=openwrt%2Fstaging%2Fblogic.git

mtd: nand: jz4740_nand: 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.
