Subject: xfs: don't cast inode_log_items to get the log_item
X-Git-Tag: v5.4-rc1~517^2~60
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b3b14aacc6765eb908f13d0422d9b2d0cd822e14;p=platform%2Fkernel%2Flinux-rpi.git

xfs: don't cast inode_log_items to get the log_item

The cast is not type safe, and we can just dereference the first
member instead to start with.
