Kees Cook 0ed2dd03b9 treewide: Use struct_size() for devm_kmalloc() and friends

Marek Szyprowski ce3bb8f554 clk: samsung: s5pv210-audss: Convert to the new clk_hw API 
Clock providers should use the new struct clk_hw based API, so convert
Samsung S5PV210 Audio Subsystem clock provider to the new approach.

Paul Gortmaker 4c7c28ffe9 clk: samsung: make clk-s5pv210-audss explicitly non-modular 
The Kconfig currently controlling compilation of this code is:

arch/arm/mach-s5pv210/Kconfig:config ARCH_S5PV210
arch/arm/mach-s5pv210/Kconfig:  bool "Samsung S5PV210/S5PC110" if ARCH_MULTI_V7

...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.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since this code is already not using module_init, case, the init
ordering remains unchanged with this commit.

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

Stephen Boyd 6f1ed07a14 clk: samsung: Properly include clk.h and clkdev.h 
Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Only include clk.h in files that are
using it. The clkdev.h header isn't always used either, so remove
it and add in slab.h where files were relying on it to include
slab for them.
