[PATCH] efi_runtime: remove efi_runtime dkms
Ivan Hu

Thu Jul 25 08:03:25 UTC 2019
efi_runtime driver provides the runtime UEFI interfaces for fwts to test
the UEFI runtime service implementiation and has upstream in Linux 4.9 named
efi_test. All supported Ubuntu kernels have efi_test included. As a result,
this dkms is no longer required.
