[PATCH] usb: host: ehci-generic: Fix error check
Commit 81755b8c20fe ("usb: host: ehci-generic: Make resets and clocks optional") improved the error check to cover the reset property being optional. However this was using the wrong error variable for the check, so would now never fail.
Use the correct error variable for checking the result of reset_get_bulk(), to actually report genuine errors.
Fixes: 81755b8c20fe ("usb: host: ehci-generic: Make resets and clocks optional") Signed-off-by: Andre Przywara andre.przywara@arm.com --- Hi,
apologies for messing up this simple patch of mine last month. I got confused by the mixed usage of "ret" and "err" in this function. This might endorse some cleanup, but I don't dare to touch this file again, especially not that late in the cycle.
Cheers, Andre

Tom, can you pick this patch directly ?
Andre, can you send the ret/err cleanup patch as a follow up , so it can be picked after release ?
