Subject: Re: [patch 07/26] Add INIT_ARRAY() to kernel.h (update 2)

Array initializers in the body of a function causes unbalanced brackets which
syntax highlighting editors such as vim have problems with. Fix this by creating
the INIT_ARRAY() macro.

It is used to declare arguments passed as function parameters such as:
text_poke(addr, INIT_ARRAY(unsigned char, 0xf0, len), len);

Changelog :
- [len] -> []
- Remove whitespaces.
- Fixed Jan's suggestion which was not checkpatch.pl-safe.
- More informative patch header.
