Subject: [PATCH][next] pwm: core: remove redundant assignment to pointer pwm

From: Colin Ian King <colin.king@...onical.com>

The pointer pwm is being initialized with a value that is never read and
it is being updated later with a new value. The initialization is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
