Subject: [PATCH] media: vicodec: Fix error codes in probe function
Date: Tue, 07 Apr 2020 09:32:37 +0000	[thread overview]
Message-ID: <20200407093237.GN68494@mwanda> (raw)

If these functions fail then we return success, but we should instead
preserve negative error code and return that.

Fixes: fde649b418d1 ("media: vicodec: Register another node for stateless decoder")
Fixes: c022a4a95722 ("media: vicodec: add struct for encoder/decoder instance")
