[PATCH][next] phy: qcom-qusb2: fix missing assignment to an error return code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The error return code is not being assigned to ret from the call
to clk_prepare_enable and consequently the current check on ret
picks up the previous error return. Fix this by adding in the
missing assignment to ret.

Detected by CoverityScan, CID#166020 ("Logically Dead code")

Fixes: 891a96f65ac3 ("phy: qcom-qusb2: Add support for runtime PM)
