Commit Message

Jim Cromie Jan. 13, 2023, 7:30 p.m. UTC 
  currently, for verbose=3, this is logged:

 dyndbg: query 0: "class DRM_UT_CORE +p" mod:*
 dyndbg: split into words: "class" "DRM_UT_CORE" "+p"

 dyndbg: op='+'
 dyndbg: flags=0x1
 dyndbg: *flagsp=0x1 *maskp=0xffffffff

 dyndbg: parsed: func="" file="" module="" format="" lineno=0-0 class=DRM_UT_CORE
 dyndbg: no matches for query
 dyndbg: no-match: func="" file="" module="" format="" lineno=0-0 class=DRM_UT_CORE
 dyndbg: processed 1 queries, with 0 matches, 0 errs

This patch:

shrinks 3 lines of 2nd stanza to single line

drops 2 middle lines of 3rd stanza
 3 differs from 1 only by status
 2 is just status, retold in 4, with more info.
