[PATCH v3] staging: bcm2835-audio: Remove the initialization of static pointers.

[AbdAllah-MEZITI <abdallah.meziti.pro@gmail.com>]

In C a static pointer will be initialized to NULL.
The §6.7.8 of the ISO/IEC 9899:1999 (E) document says that:
If an object that has static storage duration is not initialized
explicitly, then:
 __ if it has pointer type, it is initialized to a null pointer.

Signed-off-by: AbdAllah-MEZITI <abdallah.meziti.pro@gmail.com>

v2: -fix the line-wrapping of the changelog.
    -fix the ref. documentation: C99 standards release,
	and not the draft.
    -this patch is the Task 10 Eudyptula Challenge
	that only fix one code style problem.
v3: -fix the subject prefix: must be based on the previous submissions.
