Description

In the Linux kernel, the following vulnerability has been resolved: Input: cyapa - add missing input core locking to suspend/resume functions Grab input->mutex during suspend/resume functions like it is done in other input drivers. This fixes the following warning during system suspend/resume cycle on Samsung Exynos5250-based Snow Chromebook: ------------[ cut here ]------------ WARNING: CPU: 1 PID: 1680 at drivers/input/input.c:2291 input_device_enabled+0x68/0x6c Modules linked in: ...
