The below patch is still in place so samsung-laptop will not work on
EFI.

samsung-laptop: Disable on EFI hardware
This is also before the DMI quirks, ex.
if (efi_enabled(EFI_BOOT))
return -ENODEV;
quirks = &samsung_unknown;
if (!force && !dmi_check_system(samsung_dmi_table))
return -ENODEV;
I am not aware of any updates on Samsung vs. Linux with EFI. It is
really up to Samsung to make sure their BIOS doesn't get corrupted, so I
guess this bug is a "won't fix".
