This patch fixes the calculation of the internal frequency. The value of "n" is one less than the actual divider. 0 is a valid value. An example where the internal frequency is calculated correctly can be found here: clkt_dpll.c:_dpll_test_fint() This patch is against linux-next-20110120.

scripts/get_maintainer.pl would've helped you getting a better Cc list. I'm adding linux-omap and lakml
