Subject: [PATCH] phy: qcom-qusb2: fix missing assignment of ret when calling clk_prepare_enable

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

The error return from the call to clk_prepare_enable is not being assigned
to variable ret even though ret is being used to check if the call failed.
Fix this by adding in the missing assignment.

Addresses-Coverity: ("Logically dead code")
