Subject: clocksource/drivers/samsung_pwm: Constify source IO memory
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b4318ce203db8f8b7004e7ab82a957f894660c88;p=linux.git

clocksource/drivers/samsung_pwm: Constify source IO memory

The 'source_reg' IO memory is only read, so the pointer can point to
const for safety.
