Subject: [PATCH 3/3] media: mc: Make macros to obtain containers const-aware
Date: Thu, 2 Oct 2025 13:32:55 +0300 [thread overview]
Message-ID: <20251002103256.2081947-4-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20251002103256.2081947-1-sakari.ailus@linux.intel.com>
Retain the constness of the graph objects and interfaces in macros to
obtain their containers, by switching to container_of_const().
