Subject: [PATCH v5 02/14] media: controls: Add validate failure debug message
Date: Thu, 26 Nov 2020 06:36:06 -0300 [thread overview]
Message-ID: <20201126093618.137292-3-ezequiel@collabora.com> (raw)
In-Reply-To: <20201126093618.137292-1-ezequiel@collabora.com>
Add a debug message for control validation (validate_new)
failures. This is useful to debug issues with ioctls such
as VIDIOC_TRY_EXT_CTRLS and VIDIOC_S_EXT_CTRLS.
