From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> [ Upstream commit 55f223b8b408cbfd85fb1c5b74ab85ccab319a69 ] Returning an error value in a platform driver's remove callback results in a generic error message being emitted by the driver core, but otherwise it doesn't make a difference. The device goes away anyhow. For each case where ret is non-zero the driver already emits an error message, so suppress the generic error message by returning zero unconditionally. (Side note: The return value handling was unreliable anyhow as the value returned by dwc2_exit_hibernation() was overwritten anyhow if hsotg->in_ppd was non-zero.)
