[PATCH 5.14 063/849] cavium: Return negative value when pci_alloc_irq_vectors() fails
From: Greg Kroah-Hartman
Date: Mon Nov 15 2021 - 20:46:56 EST
From: Zheyu Ma <zheyuma97@xxxxxxxxx>
[ Upstream commit b2cddb44bddc1a9c5949a978bb454bba863264db ]
During the process of driver probing, the probe function should return < 0
for failure, otherwise, the kernel will treat value > 0 as success.
