Subject: [PATCH v3 2/3] ACPI: skip IRQ1 override on Redmi Book Pro 15 2022
Date: Mon, 20 Jun 2022 23:30:44 +0800	[thread overview]
Message-ID: <20220620153045.11129-3-gch981213@gmail.com> (raw)
In-Reply-To: <20220620153045.11129-1-gch981213@gmail.com>

From: Tighe Donnelly <tighe.donnelly@protonmail.com>

The IRQ is described as (Edge, ActiveLow, Shared, ) in ACPI DSDT and
it's correct. The override makes the keyboard interrupt polarity
inverted, resulting in non-functional keyboard.
Add an entry for skipping the override.
