Subject: [PATCH v2 1/3] vt: keyboard, use BIT() macro instead of open coded variants
Date: Mon, 9 Nov 2020 12:55:59 +0200 [thread overview]
Message-ID: <20201109105601.47159-1-andriy.shevchenko@linux.intel.com> (raw)
There are few places when BIT() macro is suitable and makes code
easier to understand.
