This patch does not apply to the mainline kernel or v5.6-rc1.
Please verify:
1. If the problem is still in v5.6 (we refactored the driver to
use GPIOLIB_IRQCHIP)
Linus,
Sorry, another issue was keeping me from being able to boot 5.6-rc but
that's now understood and I can confirm the issue is not present in
v5.6-rc5
2. If not, only propose it for linux-stable v5.5 etc.
Yes, needs to be applied to v5.2, v5.3, v5.4, v5.5. I cc'd stable. If
I need to re-submit please let me know.
Cc: stable@xxxxxxxxxxxxxxx
Linus, could you ack this patch for stable?
