I've been running with this patched to my kernel for a while now.
Any particular things I should do to test?

Some background on how I got to this patch was I couldn't get the mic
to work with a TRRS pinout headset. I discovered that if I set modprobe
options for laptop-amic and dell-headset-multi in a particular order
the mic would start working. I worked backwards to find this
solution.
