From: Takashi Iwai Date: Thu, 8 Sep 2022 09:51:09 +0000 (+0200) Subject: drm/udl: Increase the default URB list size to 20 X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2a07a5ddb135e4bd15bf6468b7d2daa4deeaf07d;p=linux.git drm/udl: Increase the default URB list size to 20 It seems that the current size (4) for the URB list is too small on some devices, and it resulted in the occasional stalls. Increase the default URB list size to 20 for working around it.
