This changes DRM_UT_CORE to DRM_UT_DRIVER so our typical drm.debug=0xe becomes much more spammy.
This is what I've instructed Wambui to do in i915. It's my mistake that I haven't requested this to be pointed out in the commit message.
DRM_DEBUG() and DRM_DEBUG_DRIVER() have been conflated over the years. The former is supposed to be for drm core code only, but drivers are littered with it. I'm hoping drivers are less likely to use the new drm_dbg_core() which maps to DRM_DEBUG(). The shorter drm_dbg() is the new DRM_DEBUG_DRIVER().
If you think drm.debug=0xe is too spammy now, the fix is not to abuse DRM_UT_CORE as a spare category
That mistake was made when that category was assigned to user debug like ioctls.
Shall I send a revert to remove the spam?
Fine. Please suggest an alternative to DRM_UT_CORE to use here.
BR, Jani.
