From e33e66b1b3655d98aadebf7e22eae18077698401 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Thu, 21 Sep 2023 14:13:08 +0200 Subject: ui: Clean up local variable shadowing Local variables shadowing other local variables or parameters make the code needlessly hard to understand. Tracked down with -Wshadow=local. Clean up: delete inner declarations when they are actually redundant, else rename variables.
