Subject: hwrng: atmel - remove unnecessary platform_set_drvdata()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=19e21b1d6d51a14c79ee3bc80352d665c7772b1c;p=linux-beck.git

hwrng: atmel - 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.
