Subject: [PATCH 2/4] Input: ep93xx_keypad - use BIT() and GENMASK() macros
Date: Mon, 11 Oct 2021 18:37:33 -0700	[thread overview]
Message-ID: <20211012013735.3523140-2-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20211012013735.3523140-1-dmitry.torokhov@gmail.com>

Also drop parenthesis around macros that do not use expressions as they are
not needed.
