Subject: [PATCH] clk: imx: clk-sscg-pll: Drop unnecessary initialization
Date: Fri, 21 Feb 2020 14:59:36 +0800	[thread overview]
Message-ID: <1582268376-1672-1-git-send-email-Anson.Huang@nxp.com> (raw)

No need to initialize 'ret' in many functions, as it will get
the return value from function call, so remove the initializtion
of 'ret'.
