ACPI: resource: Add JWIPC JVC9100 to irq1_level_low_skip_override[]

[PATCH] ACPI: resource: Add JWIPC JVC9100 to irq1_level_low_skip_override[]

Posted by Ai Chao 3 weeks, 4 days ago

Like the JWIPC JVC9100 has its serial IRQ (10 and 11) described
as ActiveLow in the DSDT, which the kernel overrides to EdgeHigh which
breaks the serial.

irq 10, level, active-low, shared, skip-override
irq 11, level, active-low, shared, skip-override

Add the JVC9100 to the irq1_level_low_skip_override[] quirk table to fix
this.
