[PATCH 5.10 03/95] phy: stm32: fix an error code in probe

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

 



From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit ca1c73628f5bd0c1ef6e46073cc3be2450605b06 ]

If "index > usbphyc->nphys" is true then this returns success but it
should return -EINVAL.

Fixes: 94c358da3a05 ("phy: stm32: add support for STM32 USB PHY Controller (USBPHYC)")
