From 2d967310c49ed93ac11cef408a55ddf15c3dd52e Mon Sep 17 00:00:00 2001 From: Askar Safin safinaskar@gmail.com Date: Sat, 6 Dec 2025 18:04:13 +0000 Subject: [PATCH] gpiolib: acpi: Add quirk for Dell Precision 7780

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.
