Subject: bnx2x: return PCI_ERS_RESULT_DISCONNECT on permanent failure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=07ce50e434b62c4de05207109ecd3d615b3cce42;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

bnx2x: return PCI_ERS_RESULT_DISCONNECT on permanent failure

PCI drivers that implement the struct pci_error_handlers' error_detected
callback should return PCI_ERS_RESULT_DISCONNECT if the state passed in is
pci_channel_io_perm_failure. This patch fixes the issue for bnx2x.
