Revision 5945b2880363ed7648e62aabba770ec57ff2a316 authored by Arnaud Ebalard on 10 December 2014, 23:54:02 UTC, committed by Linus Torvalds on 11 December 2014, 01:41:15 UTC
When Intersil ISL12057 support was added by commit 70e123373c05 ("rtc: Add support for Intersil ISL12057 I2C RTC chip"), two masks for time registers values imported from the device were either wrong or omitted, leading to additional bits from those registers to impact read values: - mask for hour register value when reading it in AM/PM mode. As AM/PM mode is not the usual mode used by the driver, this error would only have an impact on an externally configured RTC hour later read by the driver. - mask for month value. The lack of masking would provide an erroneous value if century bit is set. This patch fixes those two masks.
