From 8a3876f8c79f5b4160d31d881d205b6ac76e961b Mon Sep 17 00:00:00 2001 From: Jurica Vukadin Date: Tue, 7 Mar 2023 20:40:39 +0100 Subject: [PATCH] kconfig: Update config changed flag before calling callback [ Upstream commit ee06a3ef7e3cddb62b90ac40aa661d3c12f7cabc ] Prior to commit 5ee546594025 ("kconfig: change sym_change_count to a boolean flag"), the conf_updated flag was set to the new value *before* calling the callback. xconfig's save action depends on this behaviour, because xconfig calls conf_get_changed() directly from the callback and now sees the old value, thus never enabling the save button or the shortcut. Restore the previous behaviour.
