Subject: [PATCH 2/5] media: ipu6: Tell about not being able to obtain frame descriptor
Date: Thu,  8 Oct 2026 11:52:44 +0300	[thread overview]
Message-ID: <20261008085247.798156-3-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20261008085247.798156-1-sakari.ailus@linux.intel.com>

Not being able to obtain a frame descriptor is a fatal error at this
point. The frame descriptor should be stored for the duration of the
streaming operation.
