Merge tag 'pwm/for-3.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm fix from Thierry Reding:
 "Just one bugfix for the PWM lookup table code that would cause a PWM
  channel to be set to the wrong period and polarity for non-perfect
  matches"

* tag 'pwm/for-3.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm:
  pwm: Fix period and polarity in pwm_get() for non-perfect matches
