Subject: mtd: nand: tango: Fix incorrect use of SEQIN command
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a186493237a9d8559997c2f97c33c4716d602fd2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mtd: nand: tango: Fix incorrect use of SEQIN command

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.
