This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

In commit d825db346270e ("b43: shut up clang -Wuninitialized variable
warning"), the message noted that function lpphy_papd_cal() was empty
and had an old TODO regarding its implementation. As the reverse
engineering project that created the LP-PHY version of this driver
has not been active for some time, it is safe to remove this empty
function.

Clang warns about what is clearly a case of passing an uninitalized
variable into a static function:
drivers/net/wireless/broadcom/b43/phy_lp.c:1852:23: error: variable 'gains' is uninitialized when used here
[-Werror,-Wuninitialized]
lpphy_papd_cal(dev, gains, 0, 1, 30);
^~~~~
drivers/net/wireless/broadcom/b43/phy_lp.c:1838:2: note: variable 'gains' is declared here
struct lpphy_tx_gains gains, oldgains;
^
1 error generated.
However, this function is empty, and its arguments are never evaluated,
so gcc in contrast does not warn here. Both compilers behave in a
reasonable way as far as I can tell, so we should change the code
to avoid the warning everywhere.
We could just eliminate the lpphy_papd_cal() function entirely,
given that it has had the TODO comment in it for 10 years now
and is rather unlikely to ever get done. I'm doing a simpler
change here, and just pass the 'oldgains' variable in that has
been initialized, based on the guess that this is what was
originally meant.

to internally implemented one, so use it and drop the duplicate

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.
