I didn't see any warning with gcc 9.2 / 8.3 / 7.4 /6.5. Sorry for not giving detail. If I applied PICe XHCI support [1], and build rpi_4_32b, then I got related warning. If [1] is not applied, then this can be ignored.

If you have the same finding there then we should include your patch to the series. Please check and follow up there if necessary.
