Removing the != NULL is fine, but the *opt != 0 should be changed to (*opt != '\0'). There are times where comparing against zero helps readability. I wrote a blog about this, but I had forgotten the case with the NUL terminator... https://staticthinking.wordpress.com/2024/02/20/when-to-use-0/ regards, dan carpenter

Replace '(foo != NULL)' with '(foo)' and 'x != 0' with 'x' to adhere to the coding standards. Signed-off-by: Chandra Pratap <chandrapratap3519@gmail.com> --- drivers/staging/sm750fb/sm750.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
