This is not a good changelog since it does not describe what the problem with the driver is or how the change fixes it - it just says that there is a problem. > This is the warning logs when performing mount/umount then remount the device with jffs2 format: > "root@linaro-naro:~# mount -t jffs2 /dev/mtdblock2 /mnt/media > [ 3839.928013] jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x03b40000: 0x1900 instead > [ 3839.956515] jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x03b40004: 0x000c instead Please think hard before including long log messages in upstream reports, they often contain almost no useful information relative to their size so often obscure the relevant content in your message.
