From 12d0b8f5f07b76d7447d60f7528d578233553909 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 22 Feb 2017 17:12:39 +0200 Subject: [PATCH] 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).
