[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:

31 | Q: Module yealink compiled and installed without any problem but phone | ||
32 | is not initialized and does not react to any actions. | ||
33 | A: 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. | ||
38 | |||
39 | Q: Phone is working now (displays version and accepts keypad input) but I can't | ||
40 | find the sysfs files. | ||
41 | A: 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. | ||
