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

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 62c552070a980363d55a6082b432ebd1cade7a6e upstream.
The linear_conf() returns error pointers, it doesn't return NULL. Update
the error checking to match.
Fixes: 127186cfb184 ("md: reintroduce md-linear")
