Subject: [PATCH 1/3] libnvdimm: provide module_nd_driver wrapper
Date: Wed, 14 Mar 2018 19:25:06 +0100	[thread overview]
Message-ID: <20180314182508.10351-2-jthumshirn@suse.de> (raw)
In-Reply-To: <20180314182508.10351-1-jthumshirn@suse.de>

Provide a module_nd_driver() wrapper over simple nd_driver_register()
nd_driver_unregister() combinations in module_init() and module_exit()
respectively.

Note an explicit nd_driver_unregister() had to be implemented as nd
bus drivers did call device_unregister() direcly in the module_exit()
function.
