Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next

The unwanted frame types are already handled in 'default' case
of the switch/case below.
The str_ptr is allocated but it can be leaked if the length check
fails in the REQUEST/RESP cases. Fix it by allocating sta_ptr
after the length checks.

The function brcmf_p2p_detach() was only called in error flow of the
brcmf_cfg80211_attach() routine, but it also needs to be called
upon brcmf_cfg80211_detach().

Instead of waiting for IFF_UP of the primary net device to determine
the band and channel information of the wiphy structure, this is now
done during driver initialization in brcmf_cfg80211_attach(). The
channel information is obtained from the device and the 2G band is
updated when 40MHz bandwidth is enabled for that band. Before this
change the band and channel objects were common between multiple
brcmfmac devices in the system, which make that information rather
unreliable. That is also fixed with this reworked implementation.

Reworked the debugfs functions in the driver making it easier for
other driver parts to add a debugfs entry and keeping the information
they want to expose in debugfs private, ie. not in a header.

This is accomplished by providing the function brcmf_debugfs_add_entry()
in which the caller provides a read function in which they provide the
content. The debugfs function will take care of creating the debugfs
entry and cleaning up upon removal.

Sometimes pending internal scan commands are delayed to give
preference to Tx traffic. 'scan_processing' flag has been
checked at the beginning of delay timer routine to know if in the
meantime scan operation has been cancelled.

There is a corner case where pending scan commands are emptied
after scan_processing flag check is passed. In this case
wrong pointer returned by list_first_entry() is passed to
list_del() which causes system hang.

This patch fixes the issue by adding list_empty() check.
