Subject: [PATCH] phy: rockchip-inno-usb2: remove redundant assignment to variable delay
Date: Sat, 11 Dec 2021 18:00:54 +0000	[thread overview]
Message-ID: <20211211180054.525368-1-colin.i.king@gmail.com> (raw)

Variable delay is being assigned to zero and the code falls through to
the next case in a switch statement that returns out of the function.
The variable is never read in this scenario and so the assignment is
redundant and can be removed.

Cleans up scan-build static analysis warning:
drivers/phy/rockchip/phy-rockchip-inno-usb2.c:753:3: warning: Value
stored to 'delay' is never read [deadcode.DeadStores]
