It's declared in the later versions of the patch but here it was not and It was causing compilation errors and adding the function manually from the later version causes seg faults. From what I see it's not required in dwl 0.7 with wlroots 0.18
I just removed the line and kept the patch as it is to keep the credits for who made this update and also I tested it and it worked with no problem.
Compiles against dwl 0.7 with wlroots release <=0.18.1

tablet-input. (https://codeberg.org/dwl/dwl-patches/issues/141)
