Subject: [PATCH net v1] net:wireless:Fix an NULL vs IS_ERR() bug for debugfs_create_dir()
Date: Thu, 13 Jul 2023 11:03:44 +0800	[thread overview]
Message-ID: <20230713030358.12379-1-machel@vivo.com> (raw)

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.

Signed-off-by: Wang Ming <machel@vivo.com>

Fixes: e5facc75fa91 ("ath9k_htc: Cleanup HTC debugfs")
