Subject: [PATCH] clk: actions: remove redundant assignment after a mask operation
Date:   Mon, 18 Apr 2022 15:15:37 +0100

The assignment operation after a & mask operation is redundant,
the &= operator can be replaced with just the & operator.

Cleans up a clang-scan warning:
drivers/clk/actions/owl-pll.c:28:9: warning: Although the value
stored to 'mul' is used in the enclosing expression, the value is
never actually read from 'mul' [deadcode.DeadStores]
