Subject: [PATCH] drm/udl: Suppress error print for -EPROTO at URB completion
Git-commit: 53593515ec1a4a5afaaa88fd4522bc4c2d7f5d9b
Patch-mainline: v6.1-rc1
References: bsc#1195917

The driver may receive -EPROTO at the URB completion when the device
gets disconnected, and it's a normal situation.  Suppress the error
print for that, too.
