Subject[PATCH] btrfs: Remove redundant assignment to ret
Date
Variable ret is set to zero, but this value is never read as it is
overwritten or not used later on, hence it is a redundant assignment
and can be removed.

Clean up the following clang-analyzer warning:

fs/btrfs/extent_io.c:5357:4: warning: Value stored to 'ret' is never
read [clang-analyzer-deadcode.DeadStores].
