[Yaffs] Seems yaffs_parse_options cann't p arse two optitons…

Hi all,

When I tried to mount yaffs2 with two options "no-checkpoint-read" "no-checkpoint-write" together on linux-2.6.22, I got failed:

  " # mount -t yaffs2 -o no-checkpoint-read,no-checkpoint-write    /dev/mtdblock9    /mnt/yaffs/</DIV>
<DIV>      yaffs: Bad mount option " "<BR>      mount: Mounting /dev/mtdblock9 on /mnt/yaffs/ failed: Invalid argument "

Both "no-checkpoint-read" and "no-checkpoint-write" are supported by yaffs2, but yaffs_parse_options failed to parse them. Seems yaffs_parse_options cann't skip the comma. I attached a patch to fix this bug.
