Subject: PCI: amd-mdb: Correct IRQ number in INTx error message
X-Git-Tag: v7.1-rc1~151^2~12^2

PCI: amd-mdb: Correct IRQ number in INTx error message

The INTx devm_request_irq() failure path logs an incorrect IRQ number. The
printed 'irq' variable refers to a previous MDB interrupt mapping and does
not correspond to the INTx IRQ being requested.

Fix the error message to report pcie->intx_irq, which is the IRQ associated
with the failing request.
