From: Pan Bian <redacted>

Function devm_ioremap() will return a NULL pointer if it fails to remap
IO address, and its return value should be validated before it is used.
However, in function gemini_rtc_probe(), its return value is not
checked. This may result in bad memory access bugs on future access,
e.g. calling the function gemini_rtc_read_time().
