From 55a95f8f58cf5c884edfe8714bf681cd17ef7242 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 26 Nov 2022 13:57:53 +0100 Subject: [PATCH] usb: Expand buffer size in usb_find_and_bind_driver() The "generic_bus_%x_dev_%x" string which is printed into this buffer can be up to 34 characters long ("generic_bus_12345678_dev_12345678"). The buffer would be clipped by snprintf() if both %x were at maximum range. Make sure the buffer is long enough to cover such possibility.
