Subject: [PATCH v2] media: verisilicon: Explicitly disable selection api ioctls for decoders
Date: Thu, 28 Aug 2025 15:49:18 +0200 [thread overview]
Message-ID: <20250828134918.1857791-1-paulk@sys-base.io> (raw)
Call the dedicated v4l2_disable_ioctl helper instead of manually
checking whether the current context is an encoder for the selection
api ioctls.
