Subject: dwarf2ctf: don't leak directory fd.
X-Git-Tag: v4.1.12-92~313^2~33
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=049159c06198f0e7ec5047b689542f4139ae39ac;p=users%2Fjedix%2Flinux-maple.git

dwarf2ctf: don't leak directory fd.

We open a descriptor to the current directory in rel_abs_file_name() but
don't close it whilst we're done with resolving the path.  Plug the file
descriptor leak once we have returned to that directory.
