we should check the return value of calling function fir16_create(): a NULL
value means the memory allocation fails.
this patch also cleans up the error handling in function function oslec_create()

This define is never set in the kernel, so remove the code

This patch removes the need for the bit_operations.h include file which
can now be deleted. It also contains some minor corrections to comments
(typos and alignment of ASCII formulas). I have also removed some #if
lines that were not necessary.
I have tested the patch using a unit test module that runs in kernel
mode and have verified that the patched code gives identical results to
the previous version using a 8000 sample input sequence. Let me know if
you want this unit test, it runs automatically when the module is
insmod-ed and outputs a go/no go result:
# insmod oslec.ko
# dmesg

It's all just minor comment spacing issues. This patch fixes
up the remaining ones and now the code is checkpatch.pl clean.

I have just had a bug fix submitted for Oslec which I have applied to
Oslec SVN. The bug can potentially stops the echo canceller adapting
after a few seconds, although it hasn't caused many problems in
practice.

This patch removes the very noisy "end of function" markers that are

This patch removes the malloc()/free() macro wrappers and converts
call-sites to use kcalloc() and kzalloc() where appropriate. I also
fixed up out-of-memory error handling in couple of places where it was
broken.
