Subject: [PATCH v2 3/8] serial: core: use octal permissions on module param
Date: Fri, 14 Feb 2020 13:43:34 +0200	[thread overview]
Message-ID: <20200214114339.53897-4-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200214114339.53897-1-andriy.shevchenko@linux.intel.com>

Symbolic permissions 'S_IRUSR | S_IRGRP' are not preferred.
Use octal permissions '0440'. This also makes code shorter.
