ide/atapi: add support for GET EVENT STATUS NOTIFICATION
The GET EVENT STATUS NOTIFICATION is a mandatory command according to MMC-3, even if event status notification is not supported. This patch adds support for this command. It returns NEA ("No Event Available") with an empty "Supported Event Classes" to show that it doesn't event support status notification. If asychronous operation is requested, which requires NCQ support, it returns an error according to the specifications. This fixes HAL support on FreeBSD and derivatives, which fill up the logs every second with: acd0: FAILURE - unknown CMD (0x03) ILLEGAL REQUEST asc=0x20 ascq=0x00 Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
