Clang warns: drivers/usb/gadget/udc/s3c2410_udc.c:255:11: warning: comparison of address of 'ep->queue' equal to a null pointer is always false [-Wtautological-pointer-compare] if (&ep->queue == NULL) ~~~~^~~~~ ~~~~ 1 warning generated. It is not wrong, queue is not a pointer so if ep is not NULL, the address of queue cannot be NULL. No other driver does a check like this and this check has been around since the driver was first introduced, presumably with no issues so it does not seem like this check should be something else. Just remove it. Commit afe956c577b2d ("kbuild: Enable -Wtautological-compare") exposed this but it is not the root cause of the warning.

The USB role callback functions had a parameter pointing to the parent device (struct device) of the switch. The assumption was that the switch parent is always the controller. Firstly, that may not be true in every case, and secondly, it prevents us from supporting devices that supply multiple muxes.

2020-03-04usb: gadget: net2280: Distribute switch variables for initializationKees Cook1-3/+2
Variables declared in a switch statement before any case statements cannot be automatically initialized with compiler instrumentation (as they are not part of any execution flow). With GCC's proposed automatic stack variable initialization feature, this triggers a warning (and they don't get initialized). Clang's automatic stack variable initialization (via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also doesn't initialize such variables[1]. Note that these warnings (or silent skipping) happen before the dead-store elimination optimization phase, so even when the automatic initializations are later elided in favor of direct initializations, the warnings remain. To avoid these problems, move such variables into the "case" where they're used or lift them up into the main function body. drivers/usb/gadget/udc/net2280.c: In function ‘handle_stat0_irqs_superspeed’: drivers/usb/gadget/udc/net2280.c:2871:22: warning: statement will never be executed [-Wswitch-unreachable] 2871 | struct net2280_ep *e; | ^ [1] https://bugs.llvm.org/show_bug.cgi?id=44916 Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Alan Stern <stern@rowland.harvard.edu> Link: https://lore.kernel.org/r/202002201515.DFC51CF@keescook Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
