Subject[PATCH 35/42] rtc: rtc-stmp3xxx: remove unnecessary platform_set_drvdata()
Date
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.
