Since the debugfs_create_dir() never returns a null pointer, checking the return value for a null pointer is redundant. Since debugfs_create_file() can deal with a ERR_PTR() style pointer, drop the check. Signed-off-by: Li Zetao <redacted>
Thank you for your patch, I've applied this patch to my review-hans branch: https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans Note it will show up in my review-hans branch once I've pushed my local branch there, which might take a while. Once I've run some tests on this branch the patches there will be added to the platform-drivers-x86/for-next branch and eventually will be included in the pdx86 pull-request to Linus for the next merge-window. Regards, Hans
