Subject: rtc: rtc-jz4740: remove unnecessary platform_set_drvdata()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2ce5413d9ef3cf177b27edfaf7d7a3b056834fea;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

rtc: rtc-jz4740: remove unnecessary platform_set_drvdata()

The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
= NULL when no driver is bound").  Thus, it is not needed to manually
clear the device driver data to NULL.
