[RFC] sound: ppc: keywest: check if DEQ was already instantiated

Wolfram Sang
Due to changes in i2c-powermac, for some Macs the DEQ is instantiated
now in i2c-powermac while some need the instantiation here in the
keywest sound driver. The proper fix is to convert this driver to AOA.
Until then support both ways of instantiation. Before this patch, some
Macs lost sound because the sound driver failed when instantiating the
DEQ for the second time.

Dan, Mark: I hope I found a generic but not too intrusive solution to the
doubled instantiation problem. Can you please test this patch on top of this
one "sound: ppc: keywest: drop using attach adapter" from last time? Check if
you have sound and send the dmesg output, please. I hope it compiles even,
couldn't test that this time.

Re: [RFC] sound: ppc: keywest: check if DEQ was already instantiated

Dan DeVoto
Hi,

I applied this patch ("check if DEQ was already instantiated") on top of
"sound: ppc: keywest: drop using attach adapter" and sound works great.
Everything works as expected.  Below is my dmesg output.

Regards,

Dan

Yes, with Dan's tested-by. This patch should get its testing cycle via
linux-next. If no regressions, then it could be considered to send this
patch (and the one it depends on) to stable. They will fix missing sound
issues which regressed ~3 years ago. I'll leave this to you, of course.

OK, I queued it to for-next branch.  Since these are for 4.2 material,
I'll give stable requests once when merged to Linus tree.

Do you think from which stable kernel version can this be applied?


thanks,

The offending commit is 3a3dd0186f619b74e61e6f29dddcaf59af7d3cac
("i2c/powermac: Improve detection of devices from device-tree") which
came in with v3.6 if I read correctly.

Just to make sure: Keep in mind that it depends on "sound: ppc: keywest:
drop using attach adapter" which needs to go to stable, then, too.
