[PATCH RFC 0/3] ARM64: bcm2837-rpi: Fix random crashes caused by i2c

[Stefan Wahren]

This patch series tries to fix the random crashes [1] which occur on the RPi 3.

The first patch fix the possible NULL pointer dereference and the rest tries
to fix the root cause of the unexpected interrupts.

Btw this should also fix the random i2c timeouts:

i2c-bcm2835 3f805000.i2c: i2c transfer timed out

In absence of a RPi 3 this is only compile tested.
