| |
It looks like an early version of the WM831x RTC driver got merged into the mfd tree without fixes for some final review comments:
- Consistently get interrupts by name. - Implement set_mmss() rather than set_time(). - Make the error checking a bit less excessive and noisy. - Clean up the private data structure.
There shouldn't be any operational effect.
