[PATCH 01/10] staging: r8188eu: Remove wrappers for kalloc() and kzalloc()

[Larry Finger]

These wrappers involve an in_interrupt() call, which is not frowned on
in the kernel. These changes decrease the size of the driver by a trivial
amount.

[PATCH 04/10] staging: r8188eu: Remove 4 empty routines from os_sep/service.c

[Larry Finger]

Routines rtw_suspend_lock_init(), rtw_suspend_lock_uninit(),
rtw_lock_suspend(), and rtw_unlock_suspend() do not conti=ain any code.
Simplify by removing them.

[PATCH 09/10] staging: r8188eu: Remove some unused and ugly macros

[Larry Finger]

This driver contains a number of macros that are intended to do endian
conversion. The first step in getting rid of them is to delete the
ones that are not used.

[PATCH 10/10] staging: r8188eu: Remove some bit manipulation macros

[Larry Finger]

This driver defines a set of macros that get or set a bitfield in the
RX and TX descriptors. Most of these have been replaced by the appropriate
use of the system macros BIT() or GENMASK().

While reworking these routines, I also fixed camel case variables and
missing spaces. Some comments were also converted to the
drivers/net/wireless preferred format.
