From 512750ef8b06290a55d749239f956f9c21d7daca Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Mon, 10 Jul 2017 15:51:38 -0700 Subject: [PATCH] lib/kstrtox.c: delete end-of-string test Standard "while (*s)" test is unnecessary because NUL won't pass valid-digit test anyway. Save one branch per parsed character.
