2017-05-18rtlwifi: btcoex: 21a 2ant: add pnp notidy to avoid LPS/IPS mismatchYan-Hsuan Chuang
When driver is going to sleep, it does not leave LPS/IPS, thus the BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex needs to clear the IPS/LPS state when it receives a pnp notify, then it can properly set up the hw when driver wakes up. Routine ex_btc8821a2ant_pnp_notify() restored.

2017-05-10Merge tag 'hwparam-20170420' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull hw lockdown support from David Howells: "Annotation of module parameters that configure hardware resources including ioports, iomem addresses, irq lines and dma channels. This allows a future patch to prohibit the use of such module parameters to prevent that hardware from being abused to gain access to the running kernel image as part of locking the kernel down under UEFI secure boot conditions. Annotations are made by changing: module_param(n, t, p) module_param_named(n, v, t, p) module_param_array(n, t, m, p) to: module_param_hw(n, t, hwtype, p) module_param_hw_named(n, v, t, hwtype, p) module_param_hw_array(n, t, hwtype, m, p) where the module parameter refers to a hardware setting hwtype specifies the type of the resource being configured. This can be one of: ioport Module parameter configures an I/O port iomem Module parameter configures an I/O mem address ioport_or_iomem Module parameter could be either (runtime set) irq Module parameter configures an I/O port dma Module parameter configures a DMA channel dma_addr Module parameter configures a DMA buffer address other Module parameter configures some other value Note that the hwtype is compile checked, but not currently stored (the lockdown code probably won't require it). It is, however, there for future use. A bonus is that the hwtype can also be used for grepping. The intention is for the kernel to ignore or reject attempts to set annotated module parameters if lockdown is enabled. This applies to options passed on the boot command line, passed to insmod/modprobe or direct twiddling in /sys/module/ parameter files. The module initialisation then needs to handle the parameter not being set, by (1) giving an error, (2) probing for a value or (3) using a reasonable default. What I can't do is just reject a module out of hand because it may take a hardware setting in the module parameters. Some important modules, some ipmi stuff for instance, both probe for hardware and allow hardware to be manually specified; if the driver is aborts with any error, you don't get any ipmi hardware. Further, trying to do this entirely in the module initialisation code doesn't protect against sysfs twiddling. [!] Note that in and of itself, this series of patches should have no effect on the the size of the kernel or code execution - that is left to a patch in the next series to effect. It does mark annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in an already existing field" * tag 'hwparam-20170420' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: (38 commits) Annotate hardware config module parameters in sound/pci/ Annotate hardware config module parameters in sound/oss/ Annotate hardware config module parameters in sound/isa/ Annotate hardware config module parameters in sound/drivers/ Annotate hardware config module parameters in fs/pstore/ Annotate hardware config module parameters in drivers/watchdog/ Annotate hardware config module parameters in drivers/video/ Annotate hardware config module parameters in drivers/tty/ Annotate hardware config module parameters in drivers/staging/vme/ Annotate hardware config module parameters in drivers/staging/speakup/ Annotate hardware config module parameters in drivers/staging/media/ Annotate hardware config module parameters in drivers/scsi/ Annotate hardware config module parameters in drivers/pcmcia/ Annotate hardware config module parameters in drivers/pci/hotplug/ Annotate hardware config module parameters in drivers/parport/ Annotate hardware config module parameters in drivers/net/wireless/ Annotate hardware config module parameters in drivers/net/wan/ Annotate hardware config module parameters in drivers/net/irda/ Annotate hardware config module parameters in drivers/net/hamradio/ Annotate hardware config module parameters in drivers/net/ethernet/ ...

2017-05-04ath10k: htc: move htc ctrl ep connect to htc_initErik Stromdahl
This patch moves the HTC ctrl service connect from htc_wait_target to htc_init. This is done in order to make sure the htc ctrl service is setup properly before hif_start is called. The reason for this is that we want the HTC ctrl service callback to be initialized before the target sends the HTC ready message. The ready message will always be transmitted on endpoint 0 (which is always assigned to the HTC control service) so it makes more sense if HTC control has been connected before the ready message is received. Since the service to pipe mapping is done as a part of the service connect, the get_default_pipe call is redundant and was removed.

2017-04-26cfg80211: add request id parameter to .sched_scan_stop() signatureArend Van Spriel
For multiple scheduled scan support the driver needs to know which scheduled scan request is being stopped. Pass the request id in the .sched_scan_stop() callback.

2017-04-26nl80211: allow multiple active scheduled scan requestsArend Van Spriel
This patch implements the idea to have multiple scheduled scan requests running concurrently. It mainly illustrates how to deal with the incoming request from user-space in terms of backward compatibility. In order to use multiple scheduled scans user-space needs to provide a flag attribute NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is treated as a legacy scan. Drivers currently supporting scheduled scan are now indicating they support a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

2017-04-26brcmfmac: Make skb header writable before useJames Hughes
The driver was making changes to the skb_header without ensuring it was writable (i.e. uncloned). This patch also removes some boiler plate header size checking/adjustment code as that is also handled by the skb_cow_header function used to make header writable.

Function create_singlethread_workqueue() will return a NULL pointer if there is no enough memory, and its return value should be validated before using.

In a000 devices we will get all nvm data from the firmware, and can save most of the parsing. Export two APIs that op mode will still use. Adjust API of init_sbands to be independent of NVM file structure so it can be used by op mode as well.

When applying no-reclaim logic to commands other than the group zero for legacy commands, commands such as 0x1c (TX_CMD in group 0) can't be used in any other group. Fix that by applying this logic only for group 0 - it's not and should never be needed for any other groups.
