rtc: gamecube: Check the return value of ioremap()
[ Upstream commit d1220e47e4bd2be8b84bc158f4dea44f2f88b226 ]
The function ioremap() in gamecube_rtc_read_offset_from_sram() can fail
and return NULL, which is dereferenced without checking, leading to a
NULL pointer dereference.
Add a check for the return value of ioremap() and return -ENOMEM on
failure.
