X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8ea86e0ba7c9d16ae0f35cb0c4165194fa573f7a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ACPI: dock: add uevent to indicate change in device status

Send a uevent to indicate a device change whenever we dock or
undock, so that userspace may now check the dock status via sysfs.
