We're seeing lots of build problems and warnings with Clang 17 and Clang nightly:
-----8<----- /builds/linux/drivers/usb/host/xhci.c:1684:37: error: variable 'slot_id' is uninitialized when used here [-Werror,-Wuninitialized] 1684 | ret = xhci_check_maxpacket(xhci, slot_id, | ^~~~~~~ /builds/linux/drivers/usb/host/xhci.c:1652:22: note: initialize the variable 'slot_id' to silence this warning 1652 | unsigned int slot_id, ep_index; | ^ | = 0 1 error generated. make[5]: *** [/builds/linux/scripts/Makefile.build:250: drivers/usb/host/xhci.o] Error 1 ----->8-----

xhci: fix possible null pointer deref during xhci urb enqueue [ Upstream commit e2e2aacf042f52854c92775b7800ba668e0bdfe4 ]Reverting the patch makes the build pass.
Thanks, will drop. Odd that gcc doesn't catch this as well :(
I have never been able to track down the reason, but gcc on many if not most architectures doesn't catch problems like this. I often see a warning pointing to a real problem on, say, parisc builds but not elsewhere, even though the compiler version is the same.
The above problem is seen because commit e34900f46cd6 ("xhci: Reconfigure endpoint 0 max packet size only during endpoint reset") removed the call to xhci_check_maxpacket(), but that commit is not in stable releases.
