The Kconfig for this driver is currently hidden with:
config EFI_ESRT
bool
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
We leave some tags like MODULE_AUTHOR for documentation purposes.
We don't replace module.h with init.h since the file already has that.

Apparently I missed some compiler warnings on 32-bit platforms, where
phys_addr_t isn't the same size as void * and I casted it to make printk
work. Obviously I should have thought "I'm printing some random type,
instead of typecasting I should check Documentation/printk-formats.txt
and see how to do it." o/~ The More You Know ☆彡 o/~
This patch also fixes one other warning about an uninitialized variable
some compiler versions seem to see. You can't actually hit the code
path where it would be uninitialized, because there's a prior test that
would error out, but gcc hasn't figured that out. Anyway, it now has a
test and returns the error at both places.

Add sysfs files for the EFI System Resource Table (ESRT) under
/sys/firmware/efi/esrt and for each EFI System Resource Entry under
entries/ as a subdir.
The EFI System Resource Table (ESRT) provides a read-only catalog of
system components for which the system accepts firmware upgrades via
UEFI's "Capsule Update" feature. This module allows userland utilities
to evaluate what firmware updates can be applied to this system, and
potentially arrange for those updates to occur.
The ESRT is described as part of the UEFI specification, in version 2.5
which should be available from http://uefi.org/specifications in early
2015. If you're a member of the UEFI Forum, information about its
addition to the standard is available as UEFI Mantis 1090.
For some hardware platforms, additional restrictions may be found at
