From 08c76e1f7d08ec9ef6481c725dc26fba4441e766 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Sun, 25 Aug 2019 13:05:46 +0300 Subject: [PATCH] devicetree: Fix improper use of chip_operations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Auto-discoverable PCI devices do not require field .enable_dev of chip_operations to be set. They are matched with PCI drivers by the use of PCI vendor and device ID fields. The name given for the chip_operations struct must match the pathname the way it is present in the devicetree.cb files. If there was no match, util/sconfig would currently choose to use the empty weak declaration it creates in static.c file.
