[PATCH 2/3] dmaengine: dw-edma: Add missing call to 'pci_free_irq_vectors()' in probe function
From: Dejin Zheng
Date: Sun Feb 14 2021 - 08:23:16 EST
Call to 'pci_free_irq_vectors()' is missing in the error handling path
of the probe function, So add it.
Fixes: 41aaff2a2ac01c5 ("dmaengine: Add Synopsys eDMA IP PCIe glue-logic")
