[PATCH 0/1] Fix DRM driver initialization failure in kernel v5.14

[Dan Moulding]

After trying out kernel v5.14-rc5 on my system, I no longer get any
display output. Checking dmesg, I found it's because my DRM driver
(nouveau) is failing at ttm_device_init. That is failing because of a
behavior change in ttm_global_init with respect to debugfs. debugfs is
disabled on my system, which causes ttm_global_init to fail. The
following patch fixes the issue by ignoring the debugfs failure, which
is expected, rather than allowing it to cause ttm_global_init to fail.

Dan Moulding (1):
  drm: ttm: Don't bail from ttm_global_init if debugfs_create_dir fails
