2015-11-30brcm80211: fix error code in brcmf_pcie_exit_download_state()Dan Carpenter1-1/+3

2015-11-30rt2x00: type bug in _rt2500usb_register_read()Dan Carpenter1-1/+4
This code causes a static checker bug. drivers/net/wireless/ralink/rt2x00/rt2500usb.c:232 _rt2500usb_register_read() warn: passing casted pointer 'value' to 'rt2500usb_register_read()' 32 vs 16. If the low 16 bits were initialized to zero then this code would only be a problem on big endian systems. But in this case this is case the low 16 bits are never initialized. This is called from a function which is created using a macro: RT2X00DEBUGFS_OPS(csr, "0x%.8x\n", u32); We end up copying uninitialized data to the user which is bogus and an information leak.

2015-11-30brcmfmac: Unify methods to define and map firmware files.Hante Meuleman6-315/+176
All bus drivers (sdio, usb and pcie) require firmware files which needs to be downloaded to the device, The definitions and mapping of device id and revision to firmware and nvram file is done by each bus driver. This patch creates common functions and defines to simplify and unify the definition of these firmware and nvram files and mapping.

2015-11-30brcmfmac: Change error print on wlan0 existence.Hante Meuleman1-3/+4
During initialization of the device, but also on some other moments the driver prints an error that the netdev already exists. This is a result of the way the driver is initializing the firmware and not really an error. The code is not treating it as an error either. This error print has resulted in many questions by users and is confusing and incorrect. This patch changes the error log into a debug info log.

FWIL is always mapping back errors to EBADE. This is not very conventient when trying to understand problems by reading logs.

2015-11-26iwlwifi: mvm: Enable MPLUT only on supported hwAvri Altman3-4/+10
When there's a bt-wifi contention that requires arbitration, we use a priority-based mechanism to decide which comm wins. Over time, use cases become more and more complex, with multiple concurrent active links with different traffic types and different QoS requirements, on both WiFi and BT sides. This, in turn, requires us to elaborate our prioritization mechanism. However, our legacy products included hw that does not supports this, so selectively enable this on specific hw - as signaled by the firmware.
