[v2,0/3] isa: Make the remove callback for isa drivers return void

Commit Message

Uwe Kleine-König Jan. 22, 2021, 9:24 a.m. UTC

Hello,

changes since v1
(https://lore.kernel.org/r/[e-mail]):
 - fix build failure, found by the kernel test robot
   (my grep missed the struct isa_driver embedded in struct
   radio_isa_driver). For this I introduced patch 2 and adapted patch 3
   a bit. An interdiff is below.
 - Added Acks/Reviews by Guenter Roeck, William Breathitt Gray, Marc
   Kleine-Budde, Wolfram Sang and Takashi Iwai <[e-mail]>

The base-commit I specified (by hand *sigh*) in v1 was broken, must be a
cut-n-paste-error, sorry for that.

Takashi suggested to take this series via sound.git given that this is
the most affected tree. This is fine for me. Otherwise I can also
provide an immutable branch. For both variants we still need a few acks
though.

Best regards
Uwe

Now I applied all three patches to my sound.git tree.
It's found in isa-void-remove-callback signed tag, in case anyone else
wants to merge in.  The branch is based on 5.11-rc4.
