This is not only about the one-element arrays. These fixes (together with commits 434fb1e7444a and 96e27e8d919e) allow us to fix more than a dozen of these out-of-bounds warnings: drivers/gpu/drm/radeon/ni_dpm.c:2521:20: warning: array subscript 1 is above array bounds of ‘NISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’ {aka ‘struct NISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’} [-Warray-bounds] 2521 | smc_state->levels[i].dpm2.MaxPS = | ~~~~~~~~~~~~~~~~~^~~ which should be fixed in order to globally enable -Warray-bounds. :) Thanks! -- Gustavo
