[PATCH] staging: wlan-ng: Fix sparse warning: cast to restricted __le16.

[AbdAllah-MEZITI]

The same structure is used in both side, so we dont need to cast.
This will fix the following sparse warnings:
drivers/staging/wlan-ng/prism2sta.c:1139:13: warning: cast to restricted __le16
drivers/staging/wlan-ng/prism2sta.c:1150:24: warning: cast to restricted __le16

[PATCH v2] staging: sm750fb: always take the lock

[AbdAllah-MEZITI]

This patch
- Always take the lock:
The current code only takes the lock if multiple instances are in use.
This is error-prone, and confuses static analyzers.
As taking the lock in case of a single instance is harmless and cheap,
change the code to always take the lock.
- That also fix the sparse warning:
drivers/staging/sm750fb/sm750.c:159:13: warning: context imbalance in 
'lynxfb_ops_fillrect' - different lock contexts for basic block
drivers/staging/sm750fb/sm750.c:231:9: warning: context imbalance in

'lynxfb_ops_imageblit' - different lock contexts for basic block

v2:
 - add and fix the changelog text.

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

[AbdAllah-MEZITI]

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@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.
