Subject[PATCH 4.12 127/196] mtd: nand: tango: Fix incorrect use of SEQIN command
Date
4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Boris Brezillon <boris.brezillon@free-electrons.com>

commit a186493237a9d8559997c2f97c33c4716d602fd2 upstream.

SEQIN is supposed to be used when one wants to start programming a page.
What we want here is just to change the column within the page, which is
done with the RNDIN command.

Fixes: 6956e2385a16 ("mtd: nand: add tango NAND flash controller support")
