Subject: [PATCH AUTOSEL 4.9 04/26] scsi: hisi_sas: Propagate errors in interrupt_init_v1_hw()

From: Sergey Shtylyov <s.shtylyov@....ru>

[ 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...
