[PATCH] USB: Buffer overflow patch for Yealink driver
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.
