[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.

31Q: Module yealink compiled and installed without any problem but phone
32 is not initialized and does not react to any actions.
33A: If you see something like:
34 hiddev0: USB HID v1.00 Device [Yealink Network Technology Ltd. VOIP USB Phone
35 in dmesg, it means that the hid driver has grabbed the device first. Try to
36 load module yealink before any other usb hid driver. Please see the
37 instructions provided by your distribution on module configuration.

39Q: Phone is working now (displays version and accepts keypad input) but I can't
40 find the sysfs files.
41A: The sysfs files are located on the particular usb endpoint. On most
42 distributions you can do: "find /sys/ -name get_icons" for a hint.
