Subject: [PATCH v2 3/5] coresight: etm4x: use module_param instead of module_param_named
Date: Thu, 27 Jun 2019 09:35:23 +0100 [thread overview]
Message-ID: <20190627083525.37463-4-andrew.murray@arm.com> (raw)
In-Reply-To: <20190627083525.37463-1-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.
