Subject: [PATCH] mtd: rawnand: gpmi: fix dst bit offset when extracting raw payload

Re-add the multiply by 8 to "step * eccsize" to correct the destination bit offset
when extracting the data payload in gpmi_ecc_read_page_raw().

Hi Miquel

Will you please queue this for fixes? It's quite relevant for 5.10 LTS :)

Right, that will be quicker to have it in Linus' tree. I moved
the patch to the mtd/next branch.

It should be in linux-next already, I hope to collect an other
important fix this week before requesting a merge of the mtd/fixes
branch for the next -rc.

Hi Miquel,

Any guess to when the mtd/fixes branch will be pulled into Linus' tree?
