Subject[PATCH 0/3] gpio: pcie-idio-24: Fix IRQ handling
Date
This patch set fixes the irq_mask/irq_unmask functions and enables the
PLX PEX8311 local interrupts.

With the current version of the driver, gpiomon (from libgpiod) or a
poll(2) on the sysfs value are not working. According to
/proc/interrupts, there is no interruption triggered.
The main issue is that the local interrupts are not forwarded by the
PEX8311 to the PCI.

There is also two bugs:
- The IRQ mask is not correctly updated when unmasking an
interruption.
- The COS Enable Register value is not correctly updated when
masking/unmasking an interruption.

It seems this problems exist since the initial commit.
