Hi, this is your Linux kernel regression tracker. Top-posting for once, to make this easily accessible to everyone.
Miquel, Richard, Vignesh: what's up here? This patchset fixes a regression. It's quite old, so it's not that urgent, but it looked like nothing happened for two and a half week now. Or was progress made somewhere?
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
P.S.: As the Linux kernel's regression tracker I'm getting a lot of reports on my table. I can only look briefly into most of them and lack knowledge about most of the areas they concern. I thus unfortunately will sometimes get things wrong or miss something important. I hope that's not the case here; if you think it is, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.

Since commit dfeae1073583("mtd: cfi_cmdset_0002: Change write buffer to check correct value") buffered writes fail on S29GL064N. This is because, on S29GL064N, reads return 0xFF at the end of DQ polling for write completion, where as, chip_good() check expects actual data written to the last location to be returned post DQ polling completion. Fix is to revert to using chip_good() for S29GL064N which only checks for DQ lines to settle down to determine write completion.
