orangefs: fix build warning from debugfs cleanup patch
Stephen writes:
After merging the driver-core tree, today's linux-next build (x86_64
allmodconfig) produced this warning:
fs/orangefs/orangefs-debugfs.c: In function 'orangefs_debugfs_init':
fs/orangefs/orangefs-debugfs.c:193:1: warning: label 'out' defined but not used [-Wunused-label]
out:
^~~
fs/orangefs/orangefs-debugfs.c: In function 'orangefs_kernel_debug_init':
fs/orangefs/orangefs-debugfs.c:204:17: warning: unused variable 'ret' [-Wunused-variable]
struct dentry *ret;
^~~
Fix this up and change the return type of the function to void as it can
not fail, which cleans up some more code and variables as well.
