[BACKPORT PATCH] mtd: nand: fix return value check for bad block status

by Abhishek Sahu

commit e9893e6fa932f42c90c4ac5849fa9aa0f0f00a34 upstream. Positive return value from read_oob() is making false BAD blocks. For some of the NAND controllers, OOB bytes will be protected with ECC and read_oob() will return number of bitflips. If there is any bitflip in ECC protected OOB bytes for BAD block status page, then that block is getting treated as BAD.

Please apply to stable 4.9 kernel

by Juergen Gross

Hi Greg, please apply the attched backported patch to the 4.9 stable tree. It is needed to boot Xen PV guests (broken since commit c43b4ff972a986c85bdd8dc1aa05fe23b29ef99c which I didn't realize due to my kernel parameters when testing). Juergen

Backport request: bfe72442578b to 4.9.y

by Dan Rue

Hi Greg - Please apply bfe72442578b ("net: phy: micrel: fix crash when statistic requested for KSZ9031 phy") to 4.9.y. Since at least 4.9.95 (this was discussed during 4.9.95 release cycle), 'ethtool --phy-statistics eth0' causes a system crash on micrel systems. This is still happening, and this patch fixes the issue. Thanks! Dan
