rtc: as3722: correct month value
The RTC month value is 1-indexed, but the kernel assumes it is 0-indexed. This may result in the RTC not rolling over correctly. Signed-off-by: Bibek Basu <bbasu@nvidia.com> Signed-off-by: Felix Janda <felix.janda@posteo.de> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
