b83faeda02 rtlwifi: rtl8188de: Remove CamelCase variables
If a macro is in CamelCase, it it converted to upper case. Variables
and routine names are converted to lower case.

The following checkpatch exceptions are also fixed:

Note that not all checkpatch exceptions are addressed. Those will be
handled in later patches.

28484b6b37 rtl8723ae: Re-introduce the adaptive rate control
This re-introduces the function rtl8723e_dm_refresh_rate_adaptive_mask.

This function was present in a previous version of the code base,
it works just fine for me -- as long as it is not using stale data.

Unlike the original version of this function it avoids using
dm.undec_sm_pwdb when no beacon was received.

When no beacon was received, the value in dm.undec_sm_pwdb is most

Assume instead that the signal level is low.

Fix the state machine in rtl8723e_dm_cck_packet_detection_thresh
which did not clear pre_cck_fa_state when changing cur_cck_pd_state
from CCK_PD_STAGE_LOWRSSI/CCK_FA_STAGE_LOW to CCK_PD_STAGE_HIGHRSSI
and back again to CCK_PD_STAGE_LOWRSSI/CCK_FA_STAGE_LOW, the register

46b87976d7 rtl8723ae: Take the FW LPS mode handling out
This appears to trigger a firmware bug and causes severe
problems with rtl8723ae PCI devices.

When the power save mode is activated for longer periods
of time the firmware stops to receive any packets.

This problem was exposed by commit 873ffe154a ("rtlwifi:
Fix logic error in enter/exit power-save mode").

Previously the power save mode was only active rarely and
only for a short time so that the problem was not noticeable.

With commit 0a9f8f0a1b ("rtlwifi: fix btmpinfo timeout while processing
C2H_BT_INFO"), calling rtl_c2hcmd_enqueue() with rtl_c2h_fast_cmd() true,
the routine returns without freeing that skb, thereby leaking it.

This issue has been discussed at https://github.com/lwfinger/rtlwifi_new/issues/401
and the fix tested there.

c894696188 rtlwifi: rtl8821ae: replace _rtl8821ae_mrate_idx_to_arfr_id with generic version
Function _rtl8821ae_mrate_idx_to_arfr_id is functionally identical to
the generic version rtl_mrate_idx_to_arfr_id, so remove
_rtl8821ae_mrate_idx_to_arfr_id and use the generic one instead.

This also fixes a missing break statement found by CoverityScan in
_rtl8821ae_mrate_idx_to_arfr_id, namely: CID#1167237 ("Missing break
in switch")

Thanks to Joe Perches for spotting this when I submitted an earlier patch.

 * finally some of the promised HE code, but it turns
   out to be small - but everything kept changing, so
   one part I did in the driver was >30 patches for
   what was ultimately <200 lines of code ... similar
   here for this code.
 * improved scan privacy support - can now specify scan

   reducing the probe request element content
 * rfkill cleanups
 * a timekeeping cleanup from Arnd
 * various other cleanups

9a98302de1 rtlwifi: rtl8821ae: fix firmware is not ready to run
Without this patch, firmware will not run properly on rtl8821ae, and it
causes bad user experience. For example, bad connection performance with
low rate, higher power consumption, and so on.

rtl8821ae uses two kinds of firmwares for normal and WoWlan cases, and
each firmware has firmware data buffer and size individually. Original
code always overwrite size of normal firmware rtlpriv->rtlhal.fwsize, and
this mismatch causes firmware checksum error, then firmware can't start.

In this situation, driver gives message "Firmware is not ready to run!".

This patch ensures all delayed works done before entering PS to satisfy
our expectation, so use cancel_delayed_work_sync() instead. An exception
is delayed work ips_nic_off_wq because running task may be itself, so add
a parameter ips_wq to deinit function to handle this case.

6396bb2215 treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

0a9f8f0a1b rtlwifi: fix btmpinfo timeout while processing C2H_BT_INFO
In former patch, I enqueu all C2H commands and processed by a workqueue.
In case C2H_BT_INFO will issue a H2C command to set BT reg, and wait for
a C2H ack. But it is totally impossible that C2H workqueue waits for a
C2H command, so kernel log warn
	rtlwifi: :<0> btmpinfo wait (req_num=0) timeout

Since the C2H ack command C2H_BT_MP can be safely processed in interrupt
context, add a fast command path to deal with the command.

9644032e30 rtlwifi: access skb->data to get C2H data by macro
The format of C2H data is ID(1 byte) + Length(1 byte) + value, and it is
more readable to use macros to access C2H data.
