If anyone has any objections, please let me know. ------------------ From: Uwe Kleine-König (The Capable Hub) [ Upstream commit dffd32eb2b0e714a8ae23f98518ad7152cb06369 ] Similar to the issue fixed in commit 542440fd7b30 ("regmap: maple: work around gcc-14.1 false-positive warning"), I see an uninitialized warning for upper_index and upper_last. Happens with arc-linux-gnu-gcc (Debian 15.3.0-1) 15.3.0 on an allmodconfig for ARCH=arc.
