Subject: usb: gadget: g_dnl: hold maximum string descriptor
X-Git-Url: http://git.ipfire.org/?p=people%2Fms%2Fu-boot.git;a=commitdiff_plain;h=12d0b8f5f07b76d7447d60f7528d578233553909

usb: gadget: g_dnl: hold maximum string descriptor

A USB String descriptor can be up to 255 characters long and it's not
NULL terminated according to the USB spec. This means our
MAX_STRING_SERIAL should be 256 (to cope with NULL terminator).
