Hi all, sorry to bump this, but I wonder whether I could help by submitting a [PATCH] reverting the buggy change from 7d95fb7 ? As discussed in https://bugzilla.kernel.org/show_bug.cgi?id=199323 , the widespread card is unusable since 7d95fb7 . Please include me in any replies, I am not subscribed to the list.
