Subject: ACPI: Make sure we call acpi_register_gsi() even for default PCI interrupt assignment
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7be426c6e3a8ad7dcc8791589cea8af7aaafdf6f;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ACPI: Make sure we call acpi_register_gsi() even for default PCI interrupt assignment

That's the part that keeps track of the ELCR register, and we want to
make sure that the PCI interrupts are properly marked level/low.
