usb: dwc3: don't compile dwc3_trace() unless CONFIG_FTRACE=y
We don't need dwc3_trace() unless we're building a kernel with CONFIG_FTRACE. This patch reduces dwc3.ko text size a bit while also removing overhead of dwc3_trace() calls. text data bss dec hex filename 50796 581 0 51377 c8b1 drivers/usb/dwc3/dwc3.o 43961 581 0 44542 adfe drivers/usb/dwc3/dwc3.o.patched Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
