Subject: [RFC PATCH 3/5] soundwire: add module_sdw_driver helper macro
Date: Tue, 11 Jun 2019 11:40:41 +0100 [thread overview]
Message-ID: <20190611104043.22181-4-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20190611104043.22181-1-srinivas.kandagatla@linaro.org>
This Helper macro is for SoundWire drivers which do not do anything special in
module init/exit. This eliminates a lot of boilerplate. Each module may only
use this macro once, and calling it replaces module_init() and module_exit()
