From: David Sterba <dsterba@xxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 1932b7be973b554ffe20a5bba6ffaed6fa995cdc upstream.
A block-local variable stores error code but btrfs_get_blocks_direct may
not return it in the end as there's a ret defined in the function scope.
Fixes: d187663ef24c ("Btrfs: lock extents as we map them in DIO")
