Subject: [PATCH] [media] tua9001: Improve messages in .remove's error path
Date: Tue, 26 Oct 2021 21:40:10 +0200	[thread overview]
Message-ID: <20211026194010.109029-1-u.kleine-koenig@pengutronix.de> (raw)

If disabling the hardware fails the driver propagates the error code to
the i2c core. However this only results in a generic error message; the
device still disappears.

So instead emit a message that better describes the actual problem than
the i2c core's "remove failed (ESOMETHING), will be ignored" and return
0 to suppress the generic message.
