Series DYNDBG: opt-in class'd debug for modules, use in drm. | expand

Commit Message

Jim Cromie Aug. 5, 2022, 9:53 p.m. UTC 
These 2 macros used drm_debug_enabled() on DRM_UT_{DRIVER,ATOMIC}
respectively, replace those with drm_dbg_##cat invocations.

this results in new class'd prdbg callsites:

:#> grep nouveau /proc/dynamic_debug/control | grep class | wc
    116    1130   15584
:#> grep nouveau /proc/dynamic_debug/control | grep class | grep DRIVER | wc
     74     704    9709
:#> grep nouveau /proc/dynamic_debug/control | grep class | grep ATOMIC | wc
     31     307    4237
:#> grep nouveau /proc/dynamic_debug/control | grep class | grep KMS | wc
     11     119    1638

the KMS entries are due to existing uses of drm_dbg_kms().
