[PATCH] USB: Buffer overflow patch for Yealink driver

Browse Source 
Just a small patch that fixes a small parameter validation bug.

  drivers/usb/input/map_to_7segment.h:
    This patch fixes the broken parameter validation in the char to seg7
    conversion. This could cause out-of-bounds memory references.

  MAINTAINERS:
    Yealink maintainer info now in sorted order.

  Documentation/input/yealink.txt:
    Added a Q&A section that answers some common questions.
