From 210fedfcfc1a146faac67dddb3581c6b9dcd01b4 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Wed, 8 Jul 2026 22:37:03 +0200 Subject: string: correct prototype of strchrnul() Both glibc's (where this originated as a GNU extension) and the kernel's versions of strchrnul() return "char *", not "const char *". That also makes it consistent with the standard strchr() function.
