The function mdc_adjust_dirpages is only called on platforms which
don't have pages 4K in size which is why kbuild only reported this
for platforms like the Alpha. The problem was a typo in ordering of
variables in the beginning of a while loop. We were accessing the
dp pointer before it was kmapped.

BT_Active and BT_State are being masked with 0x00ffffff so it the subsequent
comparisons with 0xffffffff are therefore a buggy check.  Instead, check them
against 0x00ffffff.

Unfortunately I couldn't find a datasheet or hardware to see if 0xffffffff
is an expected invalid bit pattern that should be checked before BT_Active and
BT_State are masked with 0x00ffffff, so for now, this fix seems like the least
risky approach.

The Kconfig currently controlling compilation of this code is:

config FSL_MC_BUS
        bool "Freescale Management Complex (MC) bus driver"

...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 the code was already not using module_init, we don't have to change
the initcall and the init ordering remains unchanged with this commit.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

We don't replace module.h with init.h since the file does make some
references to "struct *module" for processing other modules.

Commit fadbe0cd ("staging: rtl8188eu:
Remove rtw_zmalloc(), wrapper for kzalloc()") changed all allocation
calls to be GFP_KERNEL even though the original wrapper was testing
to determine if the caller was in atomic mode. Most of the mistakes
were corrected with commit 33dc85c3
("staging: r8188eu: Fix scheduling while atomic error introduced in
commit fadbe0cd"); however, two kzalloc calls were missed as the
call only happens when the driver is shutting down.
