Bartosz, Andy, what's the status here? It looks like the patch didn't
make any progress in the past few days (or did I miss it?). I'd really
like to see this patch or a revert of 5467801f1fcb ("gpio: Restrict
usage of GPIO chip irq members before initialization") mainlined by rc4,
so Greg (CCed) can fix it in the next round of stable updates, as it
seems quite a few people are affected by the problem.

Reminder: this is one of those issue that we IMHO really should fix
quickly, as explained by a text recently added to the documentation:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/handling-regressions.rst#n131

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
