Subject: [PATCH mtd/next 1/8] mtd: Add helper macro for register_mtd_blktrans boilerplate
Date: Sun, 14 Feb 2021 00:45:53 +0800	[thread overview]
Message-ID: <20210213164600.409061-2-zhengdejin5@gmail.com> (raw)
In-Reply-To: <20210213164600.409061-1-zhengdejin5@gmail.com>

This patch introduces the module_mtd_blktrans macro which is a convenience
macro for mtd blktrans modules similar to module_platform_driver.
It is intended to be used by drivers which init/exit section does nothing
but register/unregister the mtd blktrans driver. By using this macro it is
possible to eliminate a few lines of boilerplate code per mtd blktrans
driver.
