60f59ce027 rtlwifi: rtl_usb: Fix missing entry in USB driver's private data
These drivers need to be able to reference "struct ieee80211_hw" from
the driver's private data, and vice versa. The USB driver failed to
store the address of ieee80211_hw in the private data. Although this
bug has been present for a long time, it was not exposed until
commit ba9f93f82a ("rtlwifi: Fix enter/exit power_save").

22b68b93ae rtlwifi: Fix kernel oops introduced with commit e496561473
With commit e496561473 {"rtlwifi: Use dev_kfree_skb_irq instead of
kfree_skb"), the method used to free an skb was changed because the
kfree_skb() was inside a spinlock. What was forgotten is that kfree_skb()
guards against a NULL value for the argument. Routine dev_kfree_skb_irq()
does not, and a test is needed to prevent kernel panics.

ba9f93f82a rtlwifi: Fix enter/exit power_save
In commit a5ffbe0a19 ("rtlwifi: Fix scheduling while atomic bug") and
commit a269913c52 ("rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter()
to use work queue"), an error was introduced in the power-save routines
due to the fact that leaving PS was delayed by the use of a work queue.

This problem is fixed by detecting if the enter or leave routines are
in interrupt mode. If so, the workqueue is used to place the request.
If in normal mode, the enter or leave routines are called directly.

cf4747d753 rtlwifi: Fix regression caused by commit d86e647688
In commit d86e647688 ("rtlwifi: rtl818x: constify local structures"),
the configuration struct for most of the drivers was changed to be
constant. The problem is that five of the modified drivers need to be
able to update the firmware name based on the exact model of the card.
As the file names were stored in one of the members of that struct,
these drivers would fail with a kernel BUG splat when they tried to
update the firmware name.

Rather than reverting the previous commit, I used a suggestion by
Johannes Berg and made the firmware file name pointers be local to
the routines that update the software variables.

The configuration struct of rtl8192cu, which was not touched in the
previous patch, is now constantfied.

the channels allowed for COUNTRY_CODE_ETSI were more properly suited
for China and Israel, not the EU. This problem has also been fixed.

4713bd1c74 rtlwifi: Add missing newlines to RT_TRACE calls
RT_TRACE does not add a newline to the end of a message and always
emits at KERN_DEBUG so these are susceptible to message interleaving
from other processes without the newline.

300c32ca84 rtlwifi: rtl8821ae: Fix potential race condition
Flag rfchange_inprogress in struct rtl_ps_ctl is protected by a spinlock
in most routines but not in rtl8821ae_dm_watchdog() which could
lead to a race condition. The necessary locking to prevent this condition
is added.

30462b514f rtlwifi: Remove unused parameter from rtl_ps_set_rf_state()
Commit 4b9d8d67b4 ("rtlwifi: rtl8192cu: Remove unused parameter") reworked
this routine. Those changes were later reverted by commit d3feae41a3
("rtlwifi: Update power-save routines for 062814 driver").

There were two changes in commit 4b9d8d67b4. The first of these removed
a parameter from rtl_ps_set_rf_state() that was always false. This is the
change that is restored in the current patch. A second change that reworked
the locking is still being analyzed.

In addition to removing the unused parameter, there is no need for
rtl_ps_set_rf_state() to be exported.

08aba42fcc rtlwifi: use s8 instead of char
Compiling the rtlwifi drivers for ARM with gcc -Wextra warns about lots of
incorrect code that results from 'char' being unsigned here, e.g.

realtek/rtlwifi/stats.c:31:16: error: comparison is always false due to limited range of data type [-Werror=type-limits]

This patch changes all uses of 'char' in this driver that refer to
8-bit integers to use 's8' instead, which is signed on all architectures.
