After applying this patch (I bisected the series) my Avenger96 board
started failing to probe the SPI NOR flash it has:

[    3.567876] spi-nor spi0.0: probe with driver spi-nor failed with error -95

I didn't spot anything with the code on a recheck but it's late on a
Friday so I've not looked too hard.  My other boards are all fine though
there's limited coverage.
