[PATCH] usb: common: usb-conn-gpio: Simplify some error message
Posted by Christophe JAILLET 5 days, 19 hours ago
dev_err_probe() already prints the error code in a human readable way, so
there is no need to duplicate it as a numerical value at the end of the
message.

Fixes: ddaf0d6dc467 ("usb: common: usb-conn-gpio: use dev_err_probe() to print log")

How about putting dev_err_probe() in a single line? it doesn't exceed
100 chars.
