Hi all,

In commit

  b3531c648d87 ("ALSA: control led: fix memory leak in snd_ctl_led_register")

Fixes tag

  Fixes: a135dfb5de1 ("ALSA: led control - add sysfs kcontrol LED marking layer")

has these problem(s):

  - SHA1 should be at least 12 digits long

This is probably not worth rebasing to fix, but can be avoided in the
future by setting core.abbrev to 12 (or more) or (for git v2.11 or later)
just making sure it is not set (or set to "auto").

:/ Sorry about this tag. The right SHA should be a135dfb5de15.

My bad, I must have overlooked the warning at applying.

Since it's the top commit and quite fresh (just an hour old), I'll
refresh the tree.


thanks,

Takashi

Hi Takashi,

I don't know why checkpatch.pl does not capture this warning for me.

./scripts/checkpatch.pl
0001-ALSA-control-led-fix-memory-leak-in-snd_ctl_led_regi.patch
total: 0 errors, 0 warnings, 89 lines checked

0001-ALSA-control-led-fix-memory-leak-in-snd_ctl_led_regi.patch has no
obvious style problems and is ready for submission.

Any idea?

checkpatch doesn't check it strictly, IIRC.

I'm using a script Stephen posted some time ago.  This should be
better covered generically in checkpatch, though...

linux-next: Fixes tag needs some work in the sound-current tree

Hi all,

In commit

  e1d8acf35ce7 ("Revert "ALSA: emu10k1: fix synthesizer sample playback position and caching"")

Fixes tag

  Fixes: df335e9a8b (ALSA: emu10k1: fix synthesizer sample playback position and caching, 2023-05-18)

has these problem(s):

  - SHA1 should be at least 12 digits long
    This can be fixed for the future by setting core.abbrev to 12 (or
    more) or (for git v2.11 or later) just making sure it is not set
    (or set to "auto").
  - Subject does not match target commit subject
    Just use
        git log -1 --format='Fixes: %h ("%s")'

The date field adds nothing.

Thus:

Fixes: df335e9a8bcb ("ALSA: emu10k1: fix synthesizer sample playback position and caching")
