From d20ceecd0c5370cfe6b6eee2f63fecb65222c747 Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Sun, 9 Nov 2008 18:14:07 -0300 Subject: V4L/DVB (9598): cx18: Prevent CX23418 from clearing it's outgoing ack interrupts to driver When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it also received that interrupt and cleared the flag before the linux driver could see what the interrupt was for. This fix prevents the CPU from receiving an IRQ for it's own outgoing ack's to the linux driver. This fix is critical now that the linux driver doesn't poll but relies on these ack interrupts.
