Subject: [PATCH v1 3/4] pinctrl: intel: Convert revision conditional to switch-case
Date: Thu,  7 Jan 2021 21:01:59 +0200	[thread overview]
Message-ID: <20210107190200.41221-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210107190200.41221-1-andriy.shevchenko@linux.intel.com>

switch-case is slightly better to maintain in case some new features will come
in new revisions of the hardware.
