Subject: [PATCH v10 1/5] serdev: Make .remove in struct serdev_device_driver optional
Date: Tue, 31 Oct 2017 09:36:52 -0700 [thread overview]
Message-ID: <20171031163656.24552-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20171031163656.24552-1-andrew.smirnov@gmail.com>
Using devres infrastructure it is possible to write a serdev driver
that doesn't have any code that needs to be called as a part of
.remove. Add code to make .remove optional.
