Hm.
char propname[9 + sizeof(int) * 2 + 4] = "pinctrl-";
If you absolutely want to do this you have to
#define PINCTRL_PREFIX "pinctrl-"
char propname[strlen(PINCTRL_PREFIX) + sizeof(int)*2 + 4] = PINCTRL_PREFIX;
Then add a comment above stating why you add 4.
No, I don't really.
This allocation seems unnecessary and the kasprintf isn't checked for non-null, so maybe this is better.
Another option would be to just add a NULL-check? This is definately not on a performance-critical path.
It's a defect not to check the kasprintf return before writing through it.
I submitted what I think appropriate.
Fix it as you choose. Or not.
cheers, Joe
