[PATCH v3 04/57] kbuild: Drop -Wdeclaration-after-statement https://lore.kernel.org/all/20230612093537.693926033@xxxxxxxxxxxxx/ See also: https://gcc.gnu.org/onlinedocs/gcc-13.2.0/gcc/Warning-Options.html#index-Wdeclaration-after-statement Would you like to stress a scope reduction for the affected local variable by adding any curly brackets?
