There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_completion_timeout() causing patterns like:
timeout = wait_for_completion_timeout(...)
if (!timeout) return -ETIMEDOUT;
with all kinds of permutations. Use 'time_left' as a variable to make the code
self explaining.

There are still surprisingly many non-chanctx drivers, but in
mac80211 that code is a bit awkward. Simplify this by having
those drivers assign 'emulated' ops, so that the mac80211 code
can be more unified between non-chanctx/chanctx drivers. This
cuts the number of places caring about it by about 15, which
are scattered across - now they're fewer and no longer in the
channel context handling.

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device. (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)
Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.

When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].
Fix a total of 30 warnings like these:
../drivers/net/wireless/zydas/zd1201.c:1560:2: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, struct iw_freq *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict]
(iw_handler) zd1201_set_freq, /* SIOCSIWFREQ */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~
The zd1201 Wireless Extension handler callbacks (iw_handler) use a
union for the data argument. Actually use the union and perform explicit
member selection in the function body instead of having a function
prototype mismatch.There are no resulting binary differences
before/after changes.
These changes were made partly manually and partly with the help of
Coccinelle.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

Failing to do so could cause the driver to misbehave or trigger a WARN()

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct usb_int_regs {
...
struct reg_data regs[0];
} __packed;
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following function:
static int usb_int_regs_length(unsigned int count)
{
return sizeof(struct usb_int_regs) + count * sizeof(struct reg_data);
}
with:
struct_size(regs, regs, count)

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, replace code of the following form:
sizeof(struct usb_req_write_regs) + count * sizeof(struct reg_data)
with:
struct_size(req, reg_writes, count)
This code was detected with the help of Coccinelle.

lockdep_assert_held() is better suited to checking locking requirements,
since it won't get confused when someone else holds the lock. This is
also a step towards possibly removing spin_is_locked().

The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

The get_seconds() function is deprecated because of the y2038 overflow.
In zd1211rw we don't even care about the absolute value, so this is
not a problem, but it's equally trivial to change to the non-deprecated
ktime_get_seconds().

Lots of the wireless driver vendor Kconfig symol help text says
"questions about cards." (2 spaces between "about" and "cards")
Besides dropping one of those spaces, it also needs some other word
inserted there. Instead of putting each vendor's name there, I chose
to say "these" cards in all of the Kconfig help text.

Pointer q is initialized and then almost immediately afterwards being
re-assigned the same value. Remove the second redundant assignment.
