Subject: clocksource/drivers/fttmr010: Pass around less pointers
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3a95de59730eb9ac8dd6a367018f5653a873ecaa;p=linux.git

clocksource/drivers/fttmr010: Pass around less pointers

Just pass bool flags from the different initcalls and use the
flags to set the right pointers. This results in less pointers
passed around in init.
