Subject: [PATCH] clk: vc5: Initialize src in vc5_mux_set_parent()
Date: Fri, 14 Dec 2018 13:49:59 -0800	[thread overview]
Message-ID: <20181214214959.162744-1-sboyd@kernel.org> (raw)

It seems that it may be possible to get to the regmap update call
without ever initializing this variable, so just set it to 0 to be safe.
