[ Upstream commit ab17122e758ef68fb21033e25c041144067975f5 ]
After commit 6c11dc060427 ("scsi: hisi_sas: Fix IRQ checks") we have the
error codes returned by platform_get_irq() ready for the propagation
upsream in interrupt_init_v1_hw() -- that will fix still broken deferred
probing. Let's propagate the error codes from devm_request_irq() as well
since I don't see the reason to override them with -ENOENT...

This patch is borked too, we don't want to return 0 here...
Looks like it's broken on <=4.19, I'll drop it. Thanks!
You might to want backport the below patch (before this one),
the same way yoo did for 5.x-stable):
