devm_pinctrl_register returns an ERR_PTR in case of error and should have an IS_ERR check instead of a null check.
The Coccinelle semantic patch used to make this change is as follows: @@ expression e; @@
e = devm_pinxtrl_register(...);
Actually, there is a typo here. devm_pinxtrl_register should be devm_pinctrl_register.
julia
if(
- !e
- IS_ERR(e) ) { <+... return
- ...
- PTR_ERR(e) ; ...+> }
