ACPICA: Cleanup PM_TIMER_FREQUENCY definition. (4f842916) · Commits · 戴 / test

This is a cosmetic patch only. Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 13 lines of 20121114 divergence.diff. There is updates in ACPICA for PM_TIMER_FREQUENCY macro, this patch cleans up the usage of this macro in Linux. This patch can also reduce the source code diff between Linux and ACPICA. Signed-off-by:
