H A D | usb.c | abd7cedb Mon Oct 23 19:28:40 CDT 2017 Suneel Garapati <suneelglinux@gmail.com> cmd: usb: ignore blk, emulation devices in usb tree/info display Usb tree/info commands iterate over all usb uclass devices recursively. Blk uclass devices based on struct blk_desc are created for mass storage device, treating them as usb uclass devices based on struct usb_device and referencing usb config interface descriptors cause crash. To fix, ignore blk and usb_emul uclass devices in usb_show_info and usb_tree_graph. Also avoid addition of preamble for blk uclass child devices, otherwise tree dump gets messed up.
