[alsa-devel] [PATCH 0/2] ALSA: control: Race fix and cleanup for user ctls

[Takashi Iwai]

Hi,

there seems a possible race between addition and removal of a user ctl
element as spotted by syzkaller.  This patchset addresses it and also
provides a cleanup thereafter.  The first one should go to 4.20 while
the second one should go for 4.21.
