Subject: [PATCH] usb: dwc3: gadget: Set non EP0 max packet limit to 512B
Commit "drivers/dwc3: add a workaround for too small OUT requests"
sets max packet for OUT requests when transfer is smaller.
Until this change the default maxpacket for non EP0 EPs was 1024. This is
too much, since UMS LBA size is 512B
