From dffea443a3c4d899085f7c0d307dbb8e88ea849a Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Wed, 23 Jun 2021 16:11:58 +0300 Subject: [PATCH] w1: w1-gpio: claim the gpio with correct initial flag gpio_request_by_name should be called with proper flags. The 0 value flag is invalid, and causes bad initialization of the gpio.
