Hi Linus and Bjorn,

These two files should be it I believe:
https://android.googlesource.com/kernel/msm/+/android-9.0.0_r0.22/drivers/nfc/nq-nci.c
https://android.googlesource.com/kernel/msm/+/android-9.0.0_r0.22/drivers/nfc/ese/pn81a.c

Sorry I didn't get around to digging into this further today, I will try
to get to it in the morning.

Cheers,
Nathan
