From 354635039d935dba16ba35054b27dd6671fd3d14 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Fri, 10 May 2019 11:01:47 -0700 Subject: firmware: google: Add a module_coreboot_driver() macro and use it Remove some boiler plate code we have in three drivers with a single line each time. This also gets us a free assignment of the driver .owner field, making these drivers work better as modules.
