Subject: [PATCH 04/13] input: adxl34xx: Make adxl34x_remove() return void
Date: Mon, 11 Oct 2021 15:27:45 +0200	[thread overview]
Message-ID: <20211011132754.2479853-5-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <20211011132754.2479853-1-u.kleine-koenig@pengutronix.de>

Up to now adxl34x_remove() returns zero unconditionally. Make it return
void instead which makes it easier to see in the callers that there is
no error to handle.

Also the return value of i2c and spi remove callbacks is ignored anyway.
