The struct lu_dirpage elements in lustre_idl.h file are modified to
__le64 and __le32 types since the  elements are always converted from
litte endian to processor native format in mdc_request.c file.

The Makefile / Kconfig currently controlling compilation of this code is:

clock/Makefile:obj-$(CONFIG_INTEL_ATOMISP)     += vlv2_plat_clock.o

atomisp/Kconfig:menuconfig INTEL_ATOMISP
atomisp/Kconfig:        bool "Enable support to Intel MIPI camera drivers"

...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 was already not in use by this driver, the init
ordering remains unchanged with this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

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

Without WARN_ON(), there is no problem, so by simply replacing it with
v4l2_err(), the warnings go away. The WARN() output is also not needed
here, as we'd probably catch the problem before even getting here,

Function uses an if statement within a for loop to guard a block of
code. If 'if' statement conditional evaluates to false, loop breaks. The
same logic can be expressed by inverting the conditional and breaking
when new conditional evaluates to true. This allows the subsequent code
to be indented one level less, aiding readability. Reduced indentation
also allows for the code to be laid out more clearly and fixes two
checkpatch warnings.

Invert if statement conditional, break from for loop if new
conditional evaluates to true. Reduce indentation in subsequent code,
fix whitespace issues. Do not change program logic.
