Subject: clocksource: sh_cmt: Initialize 'max_match_value' and 'lock' in sh_cmt_setup()
X-Git-Tag: next-20130218~14^2^6~6
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6629a983206f8f6f282a88493c2f8920c0c6abee;p=karo-tx-linux.git

clocksource: sh_cmt: Initialize 'max_match_value' and 'lock' in sh_cmt_setup()

Move the setup of spinlock and max_match_value to sh_cmt_setup().
There's no need to defer those steps until sh_cmt_register().
