ACPI: video_device_list corruption
The ->cap fields of struct acpi_video_device and struct acpi_video_bus are 1B each, not 4B. The oversized memset()'s corrupted the subsequent list_head fields. This resulted in silent corruption without CONFIG_DEBUG_LIST and BUG's with it. This patch uses sizeof() to pass the proper bounds to the memset() calls and thereby correct the bugs.
