6.11-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 14e91ddd5c02d8c3e5a682ebfa0546352b459911 ]
The code seems mostly copy-pasted, with some machine drivers forgetting to test if the 'adev' result is NULL.
Add this check when missing, and use -ENOENT consistently as an error code.
