Subject: [PATCH 2/3] driver: Call remove function only when available
Date: Tue, 17 Mar 2015 07:25:53 +0100 [thread overview]
Message-ID: <1426573554-14478-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1426573554-14478-1-git-send-email-s.hauer@pengutronix.de>
The bus implementations currently call the drivers remove
hook unconditionally, but this hook is seldomly populated. Only call
it when it's actually populated.
