some trace event use an interger to to save a bit field info of gadget, also some trace save endpoint name in string forat, it all can be chagned to other way at trace event store phase. bit field can be replace with a union interger member which include multiple bit fields. ep name stringe can be replace to a interger which contaion number and dir info. v1: https://lore.kernel.org/linux-usb/20230911042843.2711-1-quic_linyyuan@xxxxxxxxxxx/ v2: fix two compile issues that COMPILE_TEST not covered https://lore.kernel.org/linux-usb/20230911112446.1791-1-quic_linyyuan@xxxxxxxxxxx/ v3: fix reviewer comments, allow bit fields work on both little and big endian Linyu Yuan (10): usb: gadget: add anonymous definition in struct usb_gadget usb: gadget: add anonymous definition in struct usb_request usb: gadget: add anonymous definition in struct usb_ep usb: udc: trace: reduce buffer usage of trace event usb: cdns3: cdnsp: reduce buffer usage of trace event usb: cdns3: trace: reduce buffer usage of trace event usb: dwc3: trace: reduce buffer usage of trace event usb: cdns2: trace: reduce buffer usage of trace event usb: mtu3: trace: reduce buffer usage of trace event usb: musb: trace: reduce buffer usage of trace event drivers/usb/cdns3/cdns3-trace.h | 93 ++++---- drivers/usb/cdns3/cdnsp-trace.h | 45 ++-- drivers/usb/dwc3/trace.h | 54 ++--- drivers/usb/gadget/udc/cdns2/cdns2-trace.h | 77 +++---- drivers/usb/gadget/udc/trace.h | 106 +++------ drivers/usb/mtu3/mtu3_trace.h | 42 ++-- drivers/usb/musb/musb_trace.h | 14 +- include/linux/usb/gadget.h | 245 +++++++++++++++++---- 8 files changed, 383 insertions(+), 293 deletions(-) -- 2.17.1
