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.
