Subject: rtc: rtc-m48t59: remove unnecessary platform_set_drvdata()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5f371582180572f06f74dcac55c54d2072e672bc;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

rtc: rtc-m48t59: 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.
