staging: rtl8723bs: simplify control flow

Checkpatch issues "WARNING: else is not generally useful after a break
or return" for the following code:

while (1) {
do_join_r = rtw_do_join(padapter);
if (do_join_r == _SUCCESS) {
break;
} else {
rtw_dec_to_roam(padapter);

if (rtw_to_roam(padapter) > 0) {
continue;
} else {
rtw_indicate_disconnect(padapter);
break;
}
}
}

We simplify this code in multiple steps. First, we remove do_join_r
variable because it is only used right after it is assigned. Second,
we remove the unnecessary else statement right after break:

while (1) {
if (rtw_do_join(padapter) == _SUCCESS)
break;
rtw_dec_to_roam(padapter);

if (rtw_to_roam(padapter) > 0) {
continue;
} else {
rtw_indicate_disconnect(padapter);
break;
}
}

Next, we move the call to rtw_do_join into the while test because the
while will loop only until the call is successful:

while (rtw_do_join(padapter) != _SUCCESS) {
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) > 0) {
continue;
} else {
rtw_indicate_disconnect(padapter);
break;
}
}

Finally, looking at the code above, it is clear that the code will
break out of the loop if rtw_to_roam call is <= 0. Hence:

while (rtw_do_join(padapter) != _SUCCESS) {
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) <= 0) {
rtw_indicate_disconnect(padapter);
break;
}
}

staging: wfx: change variable name to be consistent

Change variable name to be consistent with the naming conventions.
ssidlen was changed to ssid_len and ssidie was changed to ssid_ie to be
consistent. This makes the variables more readable. The other ssid
names in the code are separated by an underscore. For example,
bssid_filter and num_of_ssids have the ssid separated from the rest of

In rtw_free_netdev() there are two redundant tests. The first checks for
a valid pointer to a "struct net_device". This pointer is the argument
of rtw_free_netdev(). The two callers of this function already test this
parameter immediatelly before the calls. The second checks for a valid
pointer to a "struct rtw_netdev_priv_indicator". This pointer is always
valid and, even if it were not, vfree() is a no-op on NULL pointers.

Therefore the above-mentioned two "if" statements are unnecessary and
redundant. For this reason, remove these two tests.

After removing these tests there is no more need of the "RETURN" label.
Therefore, remove also the "RETURN" label.

staging: rts5208: Convert kmap() to kmap_local_page()

The use of kmap() is being deprecated in favor of kmap_local_page()
where it is feasible.

With kmap_local_page(), the mapping is per thread, CPU local and not
globally visible. Therefore rtsx_stor_access_xfer_buf() is a function
where the use of kmap_local_page() in place of kmap() is correctly
suited.

Convert to kmap_local_page() but, instead of open coding it, use the
helpers memcpy_to_page() and memcpy_from_page().

Make a minor change to a comment related to scatter-gather.
