Bhaktipriya Shridhar 40430f0ce2 staging: rtl8712: Make return of 0 explicit
Delete unnecessary local variable whose value is always 0 and
return 0 as the result.

The following Coccinelle script was used:

@@
identifier ret; expression E;
type T;
@@
(
- T ret;
|
- T ret = 0;
)

... when != \(ret=E
\|ret--\|ret++\|--ret\|++ret\|ret-=E\|ret+=E\|ret|=E\|ret&=E\)
(
?-ret = 0;
)
... when != \(ret=E
\|ret--\|ret++\|--ret\|++ret\|ret-=E\|ret+=E\|ret|=E\|ret&=E\)
(
return
- ret
+ 0
;
)

Julia Lawall 8f47c28b5a staging: rtl8712: Drop unneeded cast on netdev_priv
The result of netdev_priv is already implicitly cast to the type of the
left side of the assignment.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
type T;
T *x;
@@

x =
- (T *)
  netdev_priv(...)

Sudip Mukherjee e29d3ebcda staging: rtl8712: remove unused variables
unused variables are removed. These variables were only assigned some
values and after that they were never being used. So they are safe to
be removed , and it has been build tested.

I left a call to r8712_read32(padapter, TCR) and
r8712_read8(padapter, SDIO_HCPWM) .

r8712_read32() and r8712_read8() is ultimately calling usb_read32()
and usb_read8() respectively. and they are again calling
r8712_usbctrl_vendorreq().
this r8712_usbctrl_vendorreq() is communicating through the usb bus
and is sending and receiving the control msg.

Paul Gortmaker 9a0fbbb52a staging: delete all duplicated endian crap from rtl8712 driver
This driver had headers like big_endian.h, little_endian.h, swab.h
and yet we can throw them all in the trash can and the thing
still builds on x86-64 and ppc, just by deleting the references
to the deleted files.

Paul Gortmaker 2046782524 staging: wean rtl8712 off of its ancient duplicate of ip.h
This driver should not be carrying around ancient copies of
headers like <linux/ip.h> for its own use.  Mapping it onto
the mainline one uncovers no build issues.

Ali Bahar 359140aaea staging: r8712u: Merging Realtek's latest (v2.6.6). Updated include directives.
These are the new include directives for header files.
The following were (somehow!) not explicity in Realtek's, but proved necessary:
"linux/usb.h" is needed for usb_alloc_urb();
"linux/interrupt.h" is needed for tasklet_struct. It was often a nested
include.

Larry Finger 2865d42c78 staging: r8712u: Add the new driver to the mainline kernel
This code is for a completely new version of the Realtek 8192 USB devices
such as the D-Link DWA-130. The Realtek code, which was originally for
Linux, Windows XP and Windows CE, has been stripped of all code not needed
for Linux. In addition, only one additional configuration variable, which
enables AP mode, remains.
