The debugfs_create_dir function returns ERR_PTR in case of error and the correct way to check an error is 'IS_ERR' inline function. This patch will replace the null-comparison with IS_ERR This issue was found with the help of Coccinelle. ./drivers/net/wireless/ath/ath5k/debug.c:985:6-12: Wrong debugfs call error processing on line 985 Signed-off-by: Atul Raut <rauji.raut@gmail.com> --- drivers/net/wireless/ath/ath5k/debug.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
