Subject: rtc: do not use container_of macro as an argument for to_platform_device
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=50e49bee3fc5c0cd0aff80ebd8061f356b7b9bd8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

rtc: do not use container_of macro as an argument for to_platform_device

The to_platform_device macro itself uses container_of macro.  Nested use
of container_of macro causes following sparse warnings:

rtc-ds1553.c:259:3: warning: symbol '__mptr' shadows an earlier one
rtc-ds1553.c:259:3: originally declared here
