Subject: [PATCH] pwm: meson: remove redundant assignment to variable fin_freq

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

The variable fin_freq 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")
