Subject: [PATCH 0/4] drm/udl: Fix stray URBs and cleanup

Hi,

this is a series of fixes for UDL driver to address the leftover URBs
at suspend/resume.  It begins with the simplification of FIFO control
code with the standard wait queue, followed by the handling of pending
URBs, and replace BUG_ON() with WARN_ON() as a cleanup.
