Subject: [PATCH 3.2 36/94] Input: pwm-beeper - remove useless call to
 pwm_config()

3.2.82-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Olivier Sobrie <olivier@...rie.be>

commit d1b12075ffa808dce33dd46b7ad035bebf8da215 upstream.

Calling pwm_config() with a period equal to zero always results in
error (-EINVAL) and pwm chip config method is never called.
