Subject: [linux-next PATCH] samsung_pwm: fix build for CONFIG_CLKSRC_SAMSUNG_PWM=n

If CONFIG_PWM_SAMSUNG=y and CONFIG_CLKSRC_SAMSUNG_PWM=n next-20130626
build fails with the following error:

drivers/pwm/pwm-samsung.c:89:19: error: static declaration of ‘samsung_pwm_lock’ follows non-static declaration
include/clocksource/samsung_pwm.h:23:19: note: previous declaration of ‘samsung_pwm_lock’ was here

It is caused by commit 9ebe293 ("pwm: Add new pwm-samsung driver").

Fix it by adding missing ifdef.
