From 8f8fe1d458664aaa15fa82de78dfdb0eca74b2ca Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Wed, 5 Oct 2022 11:28:47 +0200 Subject: efi_driver: add init function to EFI block driver For handling added and removed block devices we need to register events which has to be done when the driver is installed. This patch only creates an empty init function that will be filled with code later on. The function needs to be called before any EFI block devices are used. Move the efi_driver_init() call to early init.
