If anyone has any objections, please let me know. ------------------ From: Wang Ming [ Upstream commit 1e4134610d93271535ecf900a676e1f094e9944c ] The debugfs_create_dir() function returns error pointers, it never returns NULL. Most incorrect error checks were fixed, but the one in ath9k_htc_init_debug() was forgotten. Fix the remaining error check.
