Only variables should be passed by reference warning

Getting the warning: "Strict warning: Only variables should be passed by reference in region_blocks_block_view() (line 123 of /.../sites/all/modules/contrib/region_blocks/region_blocks.module)."

This is due to the following line: $block['content'] = render(block_get_blocks_by_region($name));

render() is accepting a variable passed by reference, but we're passing it the result of block_get_block_by_region() which returns a value.

Storing the result of that function in a new variable and then passing the variable to render() should fix the issue. Patch on the way...
