From 97c23217f1eeff563a3fa5a5bc92a4dc85d17f67 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Thu, 22 Jun 2023 23:32:13 +0200 Subject: of: module: Export of_device_uevent() The content of of_device_uevent() is currently hardcoded in a driver that can be compiled as a module. Nothing prevents of_device_uevent() to be exported to modules, most of the other helpers in of/device.c actually are. The reason why this helper was not exported is because it has been so far only useful in drivers/base, which is built-in anyway. With the idea of getting rid of the hardcoded implementation of of_device_uevent() in other places in the kernel, let's export it to GPL modules (very much like its cousins in the same file).

NOTE: this patch isn't required for correctness but instead optimizes probe order / helps avoid deferrals.
