OMAP2 clock/powerdomain: off by 1 error in loop timeout comparisons
with while (i++ < MAX_CLOCK_ENABLE_WAIT); i can reach MAX_CLOCK_ENABLE_WAIT + 1 after the loop, so if (i == MAX_CLOCK_ENABLE_WAIT) that's still success. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
