Subject: drm/vmwgfx: Fix error printout on signals pending
From: Thomas Hellstrom <thellstrom@xxxxxxxxxx>
commit e338c4c2b620ba4e75fd3576f8142eb93be12ce3 upstream.
The function vmw_master_check() might return -ERESTARTSYS if there is a
signal pending, indicating that the IOCTL should be rerun, potentially from
user-space. At that point we shouldn't print out an error message since that
is not an error condition. In short, avoid bloating the kernel log when a
process refuses to die on SIGTERM.
