Hi Greg,
Commit fee4380f368e ("mtd: nand: pxa3xx: Fix READOOB implementation") was
apparently backported in error, it looks like it should just be
dropped here in 4.4.y.
The commit lists 'Fixes: 43bcfd2bb24a ("mtd: nand: pxa3xx: Add driver-specific
ECC BCH support")', that commit was merged into v4.14, so backporting the
fix further is probably not appropriate for 4.9 or earlier kernels either.
The duplicate case statement only happens before linux-4.6, as commit
c2cdace755b5 ("mtd: nand: pxa3xx_nand: add support for partial chunks")'
removed a previous 'case READOOB' statement in this driver, so the build
regression appears only in 4.4 but not 4.9.

Crap, I didn't notice the NAND_READOOB case was handled before 4.6.
Still, the fix is needed, which means we'll have to revert this version
and create a custom one for 4.4.
Thanks for this report.

$ git describe --contains 43bcfd2bb24a
v3.14-rc1~65^2~127
That is why I backported these patches this far.
I'll drop the patch now, but the Fixes line is the problem here :)

I think my mistake in the report was misreading v3.14 as v4.14. That means we
still need the fix, just as Boris explained, it just needs to be done
differently
for older kernels.

Hm, actually I was wrong with my Fixes tag, it seems the bug has been
introduced by 'c2cdace755b5 ("mtd: nand: pxa3xx_nand: add support for
partial chunks")', so the fix is not needed for pre-4.6 kernels.

oops, also dropped it from 4.9, so I put it back there.
