Subject: [PATCH 01/02] clocksource: Add argument to resume callback

From: Magnus Damm <damm@...nsource.se>

Pass the clocksource as an argument to the clocksource
resume callback. Needed so we can point out which CMT
channel the sh_cmt.c driver shall resume.

Signed-off-by: Magnus Damm <damm@...nsource.se>
