[BUG] ASoC: nau8821: Found a bug when removing the module
Hello,
I found a bug in the driver nau8821.
When removing the module, I got a warning:

I'm guessing you have no interrupt on this platform, or that jack detect isn't used since the driver currently only requests the interrupt when that's enabled (which is a bit dodgy but not the immediate issue). I've sent a patch
