platform-drivers: x86: pmic: Fix up bogus irq hackery
commit 456dc301([PATCH] intel_pmic_gpio: modify EOI handling following
change of kernel irq subsystem) changes
- desc->chip->eoi(irq);
+
+ if (desc->chip->irq_eoi)
+ desc->chip->irq_eoi(irq_get_irq_data(irq));
+ else
+ dev_warn(pg->chip.dev, "missing EOI handler for irq %d\n", irq);
With the following explanation:
"Latest kernel has many changes in IRQ subsystem and its interfaces,
like adding irq_eoi" for struct irq_chip, this patch will make it
support both the new and old interface."
This is completely bogus.
#1) The changelog does not match the patch at all
#2) This driver relies on the assumption that it sits behind an eoi
capable interrupt line. If the implementation of the underlying
chip changes from eoi to irq_eoi then this driver has to follow
that change and not add a total bogosity.
Remove the sillyness and retrieve the interrupt data from irq_desc
directly. No need to got through circles to look it up.
