Hi all,
After merging the usb tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
In file included from drivers/usb/gadget/function/f_ncm.c:27:
drivers/usb/gadget/function/f_ncm.c: In function 'ncm_opts_dev_addr_store':
drivers/usb/gadget/function/u_ether_configfs.h:243:31: error: implicit declaration of function 'hex_to_bin' [-Wimplicit-function-declaration]

LGTM. What is the procedure for this? (my first AFAIK)
I can send a patch to Greg or Kuen-Han could do that.
