Subject: usb: gadget: u_ether: use <linux/hex.h> header file
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7a7930c0f934fb0c46de6e7ca08e14e11df35dd6;p=thirdparty%2Flinux.git

usb: gadget: u_ether: use <linux/hex.h> header file

Since <linux/kernel.h> no longer includes <linux/hex.h>, any users
of the hex interfaces need to include <linux/hex.h> themselves, so
add the header file here as needed.
