From 33799a6d1aeb892862d5f69ee87195becabf8d0c Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Fri, 29 Jul 2016 13:58:46 +0530 Subject: MIPS: Modify error handling debugfs_create_file returns NULL on error so an IS_ERR test is incorrect here and a NULL check is required. The Coccinelle semantic patch used to make this change is as follows: @@ expression e; @@ e = debugfs_create_file(...); if( - IS_ERR(e) + !e ) { <+... return - PTR_ERR(e) + -ENOMEM ; ...+> } Signed-off-by: Amitoj Kaur Chawla Cc: julia.lawall@lip6.fr Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/13834/ Signed-off-by: Ralf Baechle --- arch/mips/mm/sc-debugfs.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/mips/mm') diff --git a/arch/mips/mm/sc-debugfs.c b/arch/mips/mm/sc-debugfs.c index 5eefe3281b24..01f1154cdb0c 100644 --- a/arch/mips/mm/sc-debugfs.c +++ b/arch/mips/mm/sc-debugfs.c @@ -73,8 +73,8 @@ static int __init sc_debugfs_init(void) file = debugfs_create_file("prefetch", S_IRUGO | S_IWUSR, dir, NULL, &sc_prefetch_fops); - if (IS_ERR(file)) - return PTR_ERR(file); + if (!file) + return -ENOMEM; return 0; } -- cgit v1.2.3
