Pull HID fixes from Benjamin Tissoires:

 - A couple of i2c-hid fixes (Kenny Levinsen & Nam Cao)

 - A config issue with mcp-2221 when CONFIG_IIO is not enabled
   (Abdelrahman Morsy)

 - A dev_err fix in intel-ish-hid (Zhang Lixu)

 - A couple of mouse fixes for both nintendo and Logitech-dj (Nuno
   Pereira and Yaraslau Furman)

 - I'm changing my main kernel email address as it's way simpler for me
   than the Red Hat one (Benjamin Tissoires)
