I am glad you got it working! This looks very familiar with the suggestion I sent yesterday: http://lists.infradead.org/pipermail/linux-mtd/2019-July/090655.html It is a good practice to give some credit to someone who has helped in finding the solution of your problem. Adding a Suggested-by: Fabio Estevam <[email protected]> would be nice here. This also needs a Fixes tag.
