Hi Greg KH, Sorry for the trouble, as a new contributor to kernel. Although I have readed the document that how to submit patches, I'm still missing some details. > Where is the patch version information? The new patch adds more detailed patch description and adds 'static' before 'struct usb_ss_ep_comp_descriptor ac_int_ep_desc_comp'. > Why are you setting values to 0 when you do not have to as that is the > default value? This modification is similar to uac2. On page 362 of the USB3.2 specification. bMaxBurst is 0 means that no burst transfer. bmAttributes is 0 means that no mult. So the "Maximum number of packets = (bMaxBurst + 1) x (Mult + 1)" is 1. > The above change is not needed here. Notice this modification style. thanks, Jing Leng
