Do not call get_hdr_bssid from validate_recv_data_frame.
We already distinguish between the four cases for to_ds, from_ds. Copy
the bssid address as described in the "DS bit usage" table in
include/linux/ieee80211.h.
Eventually, we should remove get_hdr_bssid (and other similar
driver-specific parsing functions).

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.

The function iterates an index from 0 to NUM_PMKID_CACHE and returns
the first index for which the condition is true. If no such index is
found, the function returns -1. Current code has a complex control
flow that obfuscates this simple task. Replace it with a loop.
Also, given the shortened function body, replace the long variable

The use of kmap() is being deprecated in favor of kmap_local_page()
where it is feasible. In file interface/vchiq_arm/vchiq_arm.c,
function free_pagelist() calls kmap() / kunmap() from two places.
With kmap_local_page(), the mapping is per thread, CPU local and not
globally visible. Therefore, free_pagelist() 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
memcpy_to_page() helper.
