From 48ab6c9c9256003a4f2d737ccdcba81e01ba4e68 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 18 Nov 2023 16:59:12 +0900 Subject: [PATCH] kconfig: massage the loop in conf_read_simple() Make the while-loop code a little more readable. The gain is that "CONFIG_FOO" without '=' is warned as unexpected data.
