There are two important patches in this patchset: updating read pointer quicker & rework of .get_station(). There are few more upstream patches that are p2p-related and weren't backported in this commit. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 46084

Subject: [PATCH] brcmfmac: remove watchdog reset from
|
|
brcmf_pcie_buscoreprep()
|
|
|
|
The watchdog reset as done in brcmf_pcie_buscoreprep() is not
|
|
sufficient. It needs to modify PCIe core registers as well
|
|
which is properly done by brcmf_pcie_reset_device() after the
|
|
chip recognition is done. So the faulty watchdog reset can be
|
|
removed as it was causing driver reload to fail and hang the
|
|
system requiring a power-cycle. Instead the call to to the
|
|
brcmf_pcie_reset_device() function is done twice in the unload.
