Subject: [PATCH] mtd: nand: tango: Fix incorrect use of SEQIN command
References: bnc#1060662
Patch-mainline: 4.12.4
Git-commit: a186493237a9d8559997c2f97c33c4716d602fd2
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")
