f09dc911bd staging: r8188eu: remove ip.h header file
The struct ip_options declared in ip.h is only unsed in the optlength
macro which is also defined in ip.h and not used in the driver code.
All other definitions/declarations in ip.h are duplicated from
<include/uapi/linux/ip.h>. Remove the ip.h header file and its includes.

805ac0da01 staging: rtl8188eu: use actual request type as parameter
At the moment, usbctrl_vendorreq's requesttype parameter must be set to
1 for reading and 0 for writing. It's then converted to the actual
bmRequestType for the USB control request. We can simplify the code and
avoid this conversion if the caller passes the actual bmRequestType.

This patch is an adaptation of commit 788fde0310 ("staging: rtl8188eu:
use actual request type as parameter") for the new r8188eu driver.

9bfb54a8c8 staging: rtl8723bs: remove header file ethernet.h
The header file ehternet.h defines only two constants.

#define ETHERNET_HEADER_SIZE   14          /*  Ethernet Header Length */
#define LLC_HEADER_SIZE         6          /*  LLC Header Length */

Both are only used in the file core/rtw_recv.c and ETHERNET_HEADER_SIZE
just duplicates the in-kernel constant ETH_HLEN. Replace the usage of
ETHERNET_HEADER_SIZE with ETH_HLEN, move the definition of LLC_HEADER_SIZE
into rtw_rev.h (renamed to LLC_HEADER_LENGTH) and remove the now unused
header file ethernet.h.

07e7f36da8 staging/rtl8192u: Prefer kcalloc over open coded arithmetic
As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.

In this case these aren't actually dynamic sizes: both sides of the
multiplication are constant values. However it is best to refactor these
anyway, just to keep the open-coded math idiom out of code.

So, use the purpose specific kcalloc() function instead of the argument
size * count in the kzalloc() function.

7d761b084b staging: mt7621-pci: fix hang when nothing is connected to pcie ports
When nothing is connected to pcie ports, each port is set to reset state.
When this occurs, next access result in a hang on boot as follows:

mt7621-pci 1e140000.pcie: pcie0 no card, disable it (RST & CLK)
mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK)
mt7621-pci 1e140000.pcie: pcie2 no card, disable it (RST & CLK)
[ HANGS HERE ]

Fix this just detecting 'nothing is connected state' to avoid next accesses
to pcie port related configuration registers.

86a0727b09 staging: wlan-ng: Avoid duplicate header in tx/rx frames
Instead of open-coding the same header details in the tx/rx frames,
directly include the actual struct. Rename associated variables to the
more verbose of the two versions. This also has the benefit of being
able to replace a field-spanning memcpy() with a direct assignment,
helping clear the way for coming FORTIFY_SOURCE improvements.

"diffoscope" reports no object code differences after this change,
excepting the selection of different registers when switching from
memcpy() to direct assignment:

6277fbfdd2 staging: wlan-ng: Remove pointless a3/a4 union
There is no need for the a3/a4 union. The two structs are identical
except for the addition of a4. Excepting one place, the structs are
only ever used in the union, and the union is always allocated at full
size. The one instance of the a3-specific struct can be replaced with
the full version, as no sizing information is used. Replace the union
with the a4 version of the struct. "diffoscope" reports there are no
object code differences after this change.

41b8a93867 staging: r8188eu: remove function _rtw_zvmalloc
Remove the function _rtw_zvmalloc from os_dep/osdep_service.c, as this
function is now unused and is just an inline wrapper around vmalloc
which zeroes out the memory. All previous callers have been converted to
use vzalloc. Also remove the declaration from include/osdep_service.h.

It is considered generally bad practice to declare functions as inline in
the majority of cases, as not only can this qualifier be ignored by the
compiler but the compiler generally makes good decisions about inlining
anyway.

11d5fd313b staging: r8188eu: convert all rtw_zvmalloc calls to vzalloc calls
Convert all rtw_zvmalloc calls within the driver to use the existing
kernel vzalloc function, which has the same semantics. Also rewrite the
two places where it is mentioned in comments to say vzalloc, and remove
the redundant cast to struct adapter * in ./os_dep/usb_intf.c as vzalloc
returns void *.

The reason for the conversion is that rtw_zvmalloc is just a
preprocessor definition for _rtw_zvmalloc which itself is just an inline
wrapper around vmalloc which then zeroes the memory out. As vzalloc does
the same thing via usage of __GFP_ZERO, this code is redundant and can
subsequently be removed.
