Bug description:
[Impact]
Current 4.15 raspi2 kernel emits the following warnings when the spidev
driver is loaded:
kernel: [ 2.957689] WARNING: CPU: 3 PID: 34 at

kernel: [ 4.525991] WARNING: CPU: 3 PID: 34 at

spidev_probe+0x13c/0x1f8
[Test Case]
Boot 4.15 raspi2 kernel on a Pi 2/3 and load the spidev modules
[Fix]
This warning is triggered by an upstream change that wants a
compatible (HW) string which is a questionable requirement for a
generic driver. Caused a lot of upstream discussion with the end
result that the raspi people disabled the warning in their kernel. We
do the same on our newer kernels so lets backport that fix to 4.15.
[Regression Potential]
Changes are confined to the spidev module and only silence a warning.
No negative side-effects are expected.
