Subject: media: atomisp: add a notice about possible leak resources Author: Mauro Carvalho Chehab <[email protected]> Date: Tue May 12 14:23:28 2020 +0200 Calling acpi_bus_get_device() may end allocating resources that aren't freed. So, add a notice about that, as, if those drivers get out of staging, we may need some changes.
