Subject: [PATCH 6.6.y] gpiolib: acpi: Add quirk for Dell Precision 7780
Date: Wed, 31 Dec 2025 10:00:59 -0500 [thread overview]
Message-ID: <20251231150059.3101892-1-sashal@kernel.org> (raw)
In-Reply-To: <2025122946-phonebook-gusty-03ac@gregkh>
From: Askar Safin <safinaskar@gmail.com>
[ Upstream commit 2d967310c49ed93ac11cef408a55ddf15c3dd52e ]
Dell Precision 7780 often wakes up on its own from suspend. Sometimes
wake up happens immediately (i. e. within 7 seconds), sometimes it happens
after, say, 30 minutes.
Fixes: 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
