Re: [PATCH 2/2] mtd: rawnand: use bounce buffer when vmalloced data buf detected

[Kamal Dasu <kdasu.kdev@xxxxxxxxx>]

I was testing with UBI/UBIFS where vmalloced  data buffers can be
passed to the nand_base and then o the controller driver. Probably
applies to older kernel 4.1.

Can the Patch1/2 be accepted or you want me to send it separately by
removing the nand_base changes ?.
