This patch series has fixes for bugs in the SWIM floppy disk controller driver, including an oops and a soft lockup.
One way to apply these patches to v4.14+ is by first cherry-picking these commits: b87eaec27eca3def6c8ed617e3b1bac08d7bc715 e5f0d2e2a153b18dcf31e1a633e210c37829d759 There are of course other ways to fix the patch rejects, but this way would be convenient for me because it would simplify my own backporting.
Changes since v1: - Dropped the two IOP patches as they aren't simple fixes. This way, the entire series is suitable for stable trees. - Added Cc, Fixes, Acked-by and Reviewed-by tags.
