Fix for omap1 ams-delta irq We need to use IRQ_NOTCONNECTED instead of -EINVAL for ams_delta_modem_ports irq. * tag 'omap-for-v4.20/omap1-fix-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP1: ams-delta: Fix impossible .irq < 0 Signed-off-by: Olof Johansson <olof@lixom.net>
