Subject: [PATCH v1 2/4] spidev: Convert BUILD_BUG_ON() to static_assert()
Date: Wed, 23 Mar 2022 16:02:13 +0200 [thread overview]
Message-ID: <20220323140215.2568-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220323140215.2568-1-andriy.shevchenko@linux.intel.com>
static_assert() is a preferred method to fail build when the certain
constraints are not met. Convert BUILD_BUG_ON() to static_assert().
