Javier Martinez Canillas a20cd88e20 rtc: max77686: Use ffs() to calculate tm_wday ...

max77686_rtc_calculate_wday() is used to calculate the day of the week
to be filled in struct rtc_time but that function only calculates the
number of bits shifted.  So the ffs() function can be used to find the
first bit set instead of a special function.

[akpm@linux-foundation.org: add comment clarifying ffs() use]
