I'm afraid I'm lost in this one - which patch caused the regression and
which one fixed it?  The only patches I can immediately see in next
both introduce and then squish a similar bug, but neither of them
has hit Linus' tree yet.

Or are we dealing with what was fixed in:
c816d9e7 iio: imu: mpu6050: fix possible NULL dereferences
I had understood that one as more hypothetical than real...

Unfortunately I'm travelling and I suspect that means this will only get
in just after the release (so for 4.6.1) once I've confirmed which fixes
we actually need to backport.
