bb5b5e2104 staging: rtl8192e: Fix divide fault when calculating beacon age 
When the configuration parameter CONFIG_HZ is less that 100, the compiler
generates an error as follows:

../drivers/staging/rtl8192e/rtllib_wx.c: In function 'rtl819x_translate_scan':
../drivers/staging/rtl8192e/rtllib_wx.c:220:57: warning: division by zero [-Wdiv-by-zero]
  220 |      (jiffies - network->last_scanned) / (HZ / 100));
      |                                                         ^
In file included from ../include/linux/skbuff.h:45,
                 from ../include/linux/if_ether.h:19,
                 from ../include/linux/etherdevice.h:20,
                 from ../drivers/staging/rtl8192e/rtllib_wx.c:18:
../drivers/staging/rtl8192e/rtllib_wx.c: In function 'rtllib_wx_get_scan':
../drivers/staging/rtl8192e/rtllib_wx.c:261:70: warning: division by zero [-Wdiv-by-zero]
  261 |      (jiffies - network->last_scanned) /
      |

In fact, is HZ is not a multiple of 100, the calculation will be wrong,
but it will compile correctly.

The fix is to get rid of the (HZ / 100) portion. To decrease any round-off
errors, the compiler is forced to perform the 100 * jiffies-difference
before dividing by HZ. This patch is only compile tested.

dcb18f5140 staging: r8188eu: change return type of rtw_set_802_11_disassociate to void 
Change return type of rtw_set_802_11_disassociate to void. This function
always returns 'true' no matter what, so there is no need to return a
value, and no need to check for it in the two call sites within
rtw_wx_set_mlme. Also, as we are no longer using ret in rtw_wx_set_mlme
except as the return value, just remove it and return 0 directly.

wrap rtw_enqueue_cmd call and return -EPERM if it fails, as converting

8b550eb637 staging: rtl8192u: remove unnecessary function implementation 
This driver is a single standalone driver and does not have any loading
dependencies on another associated drivers. The build results in one
single .ko object. The current implementation of the function
ieee80211_tkip_null simply returns back to the caller without any useful
instruction executions. It does not lead to auto-loading of any other
associated modules as the initial design implementation appears to be.

Hence the call to ieee80211_tkip_null() and its implementation is
unnecessary and should be removed.

Define a struct ieee80211_mgmt in OnAction_p2p and use it to check the
destination address. This replaces a call to the driver-specific
GetAddr1Ptr function.

OnAction_p2p has a switch-case statement where only a single case is
handled. Use if instead, this makes the code shorter and easier to read.

The on_action_public function is called only by OnAction. This function
also lives in rtw_mlme_ext.c and does not check the return value from
on_action_public.

We can make on_action_public a static void function.

The ret variable is no longer needed if we don't return a value. It can
be removed.

336ccc31cd staging: rtl8712: fix potential memory leak 
In r8712_init_drv_sw(), whenever any function call returns error, it is
returned immediately without properly cleaning up the other successfully
executed functions. This can cause memory leak.

Instead of return immediately, free all the allocated buffers first.

The return value of _r8712_init_xmit_priv() is never checked and the driver
always continue execution as if all is well. This will cause problems
if, for example, buffers cannot be allocated and the driver continue and
use those buffers.

Check for return value of _r8712_init_xmit_priv() and return error (if any)
during probing.

c5a7eecdcd Revert "staging: r8712u: Tracking kmemleak false positives." 
This reverts commit 5d3da4a20a.

This commit annotated false positive for kmemleak. The reasoning is that
the buffers are freed when the driver is unloaded. However, there is
actually potential memory leak when probe fails.
