Subject: [PATCH v4 3/6] coresight: etm4x: use module_param instead of module_param_named
Date: Tue, 30 Jul 2019 13:51:54 +0100	[thread overview]
Message-ID: <20190730125157.884-4-andrew.murray@arm.com> (raw)
In-Reply-To: <20190730125157.884-1-andrew.murray@arm.com>

Given that the user-exposed module parameter for 'boot_enable' matches
the variable that it sets, let's use module_param instead of
module_param_named.

Let's also use octal permissions (checkpatch recommends this) and
provide a module parameter description.
