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 <amitoj1606@gmail.com> 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 <ralf@linux-mips.org>
