Also makes the object code smaller by 97 bytes: Before: text data bss dec hex filename 38899 8064 0 46963 b773 ./drivers/gpu/drm/radeon/r600_dpm.o After: text data bss dec hex filename 38738 8128 0 46866 b712 ./drivers/gpu/drm/radeon/r600_dpm.o (gcc version 11.2.0) Signed-off-by: Colin Ian King Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/radeon/r600_dpm.c b/drivers/gpu/drm/radeon/r600_dpm.c index fd4226b99862b..9d2bcb9551e61 100644 --- a/drivers/gpu/drm/radeon/r600_dpm.c +++ b/drivers/gpu/drm/radeon/r600_dpm.c @@ -1361,7 +1361,9 @@ u16 r600_get_pcie_lane_support(struct radeon_device *rdev, u8 r600_encode_pci_lane_width(u32 lanes) { - u8 encoded_lanes[] = { 0, 1, 2, 0, 3, 0, 0, 0, 4, 0, 0, 0, 5, 0, 0, 0, 6 }; + static const u8 encoded_lanes[] = { + 0, 1, 2, 0, 3, 0, 0, 0, 4, 0, 0, 0, 5, 0, 0, 0, 6 + }; if (lanes > 16) return 0;
