[PATCH v2 0/3] Improve drm printer code

[Michal Wajdeczko]

We already have some drm printk functions that need to duplicate
a code to get a similar format of the final result, for example:

  [ ] 0000:00:00.0: [drm:foo] bar
  [ ] 0000:00:00.0: [drm] foo bar
  [ ] 0000:00:00.0: [drm] *ERROR* foo

Add a generic __drm_dev_vprintk() function that can format the
final message like all other existing function do and allows us
to keep the formatting code in one place.

Above also allows to improve drm_dbg_printer() that today lacks
of outputing symbolic name of the caller, like drm_dbg() does.

v1: https://patchwork.freedesktop.org/series/133749/
v2: make it static, keep it simple and use braces (Jani)

Michal Wajdeczko (3):
  drm/print: Add generic drm dev printk function
