[PATCH v4 0/4] staging: rtl8192u: Fix warnings in ieee80211_crypt.c

[Navya Sri Nizamkari]

[changes in v4]
In v4 version, code indentation is changed to look better.

[changes in v3]
In v3 version, the printk functions which are changed to pr_dbg
are changed to pr_debug as pr_dbg gives a 'implicit declaration of
function' warning when you build.

[changes in v2]
In v2 version of this patchset I correct the commit message of
[PATCH 1/4] to be clearer and remove a comment from [PATCH 2/4]
whose style was changed in version v1.

[original cover letter]
This patchset removes an unnecessary comment and clears checkpatch.pl
warnings in ieee80211_crypt.c such as:
convert printk to a preferable function like netdev_dbg or pr_dbg,
replace asm header files with
linux ones, fix the quoted string split across a line.

[PATCH v4 1/4] staging: rtl8192u: Convert from printk into netdev_dbg or pr_debug

[Navya Sri Nizamkari]

As this is a network driver file, convert printk(KERN_DEBUG.. ) to
netdev_dbg if the calling function has arguments to support it else
to pr_debug , to fix the checkpatch.pl warning:

WARNING: Prefer netdev_dbg(netdev, ... then dev_dbg(dev, ... then
pr_debug(...  to printk(KERN_DEBUG ...

Changes in v4:
    - Changed code indentation.

Changes in v3:
    - Change pr_dbg to pr_debug as it gives the following warning:
      implicit declaration of function ‘pr_dbg’and change 
      subject name to reflect the change.

Changes in v2:
    - Correct the commit message to be clearer.

[PATCH v4 3/4] staging: rtl8192u: Replace asm header files with linux ones.

[Navya Sri Nizamkari]

As asm header files are included in linux header files, this patch
uses <linux/string.h> instead of <asm/string.h> and <linux/errno.h>
instead of <asm/errno.h> to fix checkpatch.pl errors:

ERROR: Use #include <linux/string.h> instead of <asm/string.h>
ERROR: Use #include <linux/errno.h> instead of <asm/errno.h>

This patch doesn't apply anymore to my tree :(
