Subject: [PATCH] PCI: Mark Ceton InfiniTV4 INTx masking as broken
Git-commit: 7c1efb686817881d7dc0b06572785ec8f17d2823
Patch-mainline: v4.16-rc1
References: bsc#1120058
PCI_COMMAND_INTX_DISABLE is writable on the Ceton InfiniTV4, indicating
that the device supports disabling the INTx# signal, but it apparently
doesn't work.
Mark the device so we know we can't use PCI_COMMAND_INTX_DISABLE to disable
its interrupts.
