Subject: [PATCH] ata: libata: Make ata_platform_remove_one return void
Date:   Fri, 12 May 2023 22:46:46 +0200
Message-Id: <20230512204646.137746-1-u.kleine-koenig@pengutronix.de>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

The function returned zero unconditionally, so the function returning an
int is something between useless and irritating. With the goal to make
platform drivers' remove function return void, it's helpful to convert
the function accordingly. This converts several drivers to the new
.remove_new callback that was introduced to smoothen the platform driver
conversion.
