hi drm folks,
Heres a small set of assorted patches which are IMO suitable for rcX; one doc fix, 2 patches folding multiple DBGs together, and a format string modification.
Jim Cromie (4): drm: fix doc grammar error amdgpu_ucode: reduce number of pr_debug calls nouveau: fold multiple DRM_DEBUG_DRIVERs together i915/gvt: remove spaces in pr_debug "gvt: core:" etc prefixes

There are blocks of DRM_DEBUG calls, consolidate their args into single calls. With dynamic-debug in use, each callsite consumes 56 bytes of callsite data, and this patch removes about 65 calls, so it saves ~3.5kb.
no functional changes.
RFC: this creates multi-line log messages, does that break any syslog conventions ?

No functional change, but an output logging content change.

It does change the output as each individual DRM_DEBUG is a call to __drm_dbg which is effectively:

ok. that would disqualify the nouveau patch too.
With DRM_USE_DYNAMIC_DEBUG, each callsite record requires 56 bytes. We can combine 12 into one here and save ~620 bytes.

Taking embedded spaces out of existing prefixes makes them better class-prefixes; simplifying the extra quoting needed otherwise:
$> echo format "^gvt: core:" +p >control vs $> echo format ^gvt:core: +p >control
Dropping the internal spaces means that quotes are only needed when the trailing space is required; they more distinctively signal that requirement.
Consider a generic drm-debug example:
# turn off ATOMIC reports echo format "^drm:atomic: " -p > control
# turn off all ATOMIC:* reports, including any sub-categories echo format "^drm:atomic:" -p > control
# turn on ATOMIC:FAIL: reports echo format "^drm:atomic:fail: " +p > control
Removing embedded spaces in the class-prefixes simplifies the corresponding match-prefix. This means that "quoted" match-prefixes are only needed when the trailing space is desired, in order to exclude explicitly sub-categorized pr-debugs; in this example, "drm:atomic:fail:".
