This is contradicting the fwnode_irq_get_byname() function documentation and can potentially be a source of errors like: int probe(...) { ... irq = fwnode_irq_get_byname(); if (irq <= 0) return irq; ... } Here we do correctly check the return value from fwnode_irq_get_byname() but the driver probe will now return success. (There was already one such user in-tree). Change the fwnode_irq_get_byname() to work as documented and make also the fwnode_irq_get() follow same common convention returning a negative errno upon failure.

The special error case where device-tree based IRQ mapping fails can't no longer be reliably detected from this return value. This yields a functional change in the driver where the mapping failure is treated as an error. The mapping failure can occur for example when the device-tree IRQ information translation call-back(s) (xlate) fail, IRQ domain is not found, IRQ type conflicts, etc. In most cases this indicates an error in the device-tree and special handling is not really required. One more thing to note is that ACPI APIs do not return zero for any failures so this special handling did only apply on device-tree based systems. Drop the special (no error, just skip the IRQ) handling for DT mapping failures as these can no longer be separated from other errors at driver side.

The special error case where device-tree based IRQ mapping fails can't no longer be reliably detected from this return value. This yields a functional change in the driver where the mapping failure is treated as an error. The mapping failure can occur for example when the device-tree IRQ information translation call-back(s) (xlate) fail, IRQ domain is not found, IRQ type conflicts, etc. In most cases this indicates an error in the device-tree and special handling is not really required. One more thing to note is that ACPI APIs do not return zero for any failures so this special handling did only apply on device-tree based systems. Drop the special handling for DT mapping failures as these can no longer be separated from other errors at driver side. Change all failures in IRQ getting to be handled by continuing without the events instead of aborting the probe upon certain errors. Signed-off-by: Matti Vaittinen Reviewed-by: Jonathan Cameron --- Revision history: v5 => v6: - Never abort the probe when IRQ getting fails but continue without events. Please note that I don't have the hardware to test this change. Furthermore, testing this type of device-tree error cases is not trivial, as the question we probably dive in is "what happens with the existing users who have errors in the device-tree". Answering to this question is not simple.
