bcache: properly initialize 'path' and 'err' in register_bcache()
[ Upstream commit 29cda393bcaad160c4bf3676ddd99855adafc72f ]
Patch "bcache: rework error unwinding in register_bcache" from
Christoph Hellwig changes the local variables 'path' and 'err'
in undefined initial state. If the code in register_bcache() jumps
to label 'out:' or 'out_module_put:' by goto, these two variables
might be reference with undefined value by the following line,
out_module_put:
module_put(THIS_MODULE);
out:
pr_info("error %s: %s", path, err);
return ret;
Therefore this patch initializes these two local variables properly
in register_bcache() to avoid such issue.
