Subject: io_uring: parenthesize io_ring_head_to_buf() expansion
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c84701cfc90a90a6a9dfbdb138706a6d79f5b186;p=thirdparty%2Flinux.git

io_uring: parenthesize io_ring_head_to_buf() expansion

Wrap the io_ring_head_to_buf() macro value in an extra pair of parentheses
so it is safe when composed into larger expressions, and to satisfy
scripts/checkpatch.pl.
