Subject: [PATCH 3/7] intel_th: Constify all drvdata references
Date: Wed, 14 Apr 2021 20:12:47 +0300 [thread overview]
Message-ID: <20210414171251.14672-4-alexander.shishkin@linux.intel.com> (raw)
In-Reply-To: <20210414171251.14672-1-alexander.shishkin@linux.intel.com>
Anything that deals with drvdata structures should leave them intact.
Reflect this in function signatures.
