drivers/staging/lustre/lustre/fid/lproc_fid.c: In function
'ldebugfs_fid_write_common':
drivers/staging/lustre/lustre/fid/lproc_fid.c:67:6: warning: variable 'rc' set
but not used [-Wunused-but-set-variable]
int rc;
We fix it by *using* the return code to help bulletproof it. It says it's
test code - it should be *more* bulletproof than production, not less.
