2016-11-19iio: accel: st_accel: inline per-sensor dataLinus Walleij
We have #defines for all the individual sensor registers and value/mask pairs #defined at the top of the file and used at exactly one spot. This is usually good if the #defines give a meaning to the opaque magic numbers. However in this case, the semantic meaning is inherent in the name of the C99-addressable fields, and that means duplication of information, and only makes the code hard to maintain since you every time have to add a new #define AND update the site where it is to be used. Get rid of the #defines and just open code the values into the appropriate struct elements. Make sure to explicitly address the .hz and .value fields in the st_sensor_odr_avl struct so that the meaning of all values is clear. This patch is purely syntactic should have no semantic effect.

2016-11-19mwifiex: reset card->adapter during device unregisterXinming Hu
card->adapter gets initialized in mwifiex_register_dev(). As it's not cleared in mwifiex_unregister_dev(), we may end up accessing the memory which is already free in below scenario. Scenario: Driver initialization is failed due to incorrect firmware or some other reason. Meanwhile device reboot/unload occurs. This is safe, now that we've properly synchronized suspend() and remove() with the FW initialization thread; now that code can simply check for 'card->adapter == NULL' and exit safely.

2016-11-19mwifiex: resolve races between async FW init (failure) and device removalBrian Norris
It's possible for the FW init sequence to fail, which will trigger a device cleanup sequence in mwifiex_fw_dpc(). This sequence can race with device suspend() or remove() (e.g., reboot or unbind), and can trigger use-after-free issues. Currently, this driver attempts (poorly) to synchronize remove() using a semaphore, but it doesn't protect some of the critical sections properly. Particularly, we grab a pointer to the adapter struct (card->adapter) without checking if it's being freed or not. We later do a NULL check on the adapter, but that doesn't work if the adapter was freed. Also note that the PCIe interface driver doesn't ever set card->adapter to NULL, so even if we get the synchronization right, we still might try to redo the cleanup in ->remove(), even if the FW init failure sequence already did it. This patch replaces the static semaphore with a per-device completion struct, and uses that completion to synchronize the remove() thread with the mwifiex_fw_dpc(). A future patch will utilize this completion to synchronize the suspend() thread as well. Signed-off-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-11-19mwifiex: check tx_hw_pending before downloading sleep confirmShengzhen Li
We may get SLEEP event from firmware even if TXDone interrupt for last Tx packet is still pending. In this case, we may end up accessing PCIe memory for handling TXDone after power save handshake is completed. This causes kernel crash with external abort. This patch will only allow downloading sleep confirm when no tx done interrupt is pending in the hardware.

2016-11-19mwifiex: Allow mwifiex early access to device structureRajat Jain
Today all the interface drivers (usb/pcie/sdio) assign the adapter->dev in the register_dev() callback, although they have this piece of info well before hand. This patch makes the device structure available for mwifiex right at the beginning, so that it can be used for early initialization if needed. This is needed for subsequent patches in this patchset that intend to unify and consolidate some of the code that would otherwise have to be duplicated among the interface drivers (sdio, pcie, usb).

2016-11-19PM / Runtime: Defer resuming of the device in pm_runtime_force_resume()Ulf Hansson
When the pm_runtime_force_suspend|resume() helpers were invented, we still had CONFIG_PM_RUNTIME and CONFIG_PM_SLEEP as separate Kconfig options. To make sure these helpers worked for all combinations and without introducing too much of complexity, the device was always resumed in pm_runtime_force_resume(). More precisely, when CONFIG_PM_SLEEP was set and CONFIG_PM_RUNTIME was unset, we needed to resume the device as the subsystem/driver couldn't rely on using runtime PM to do it. As the CONFIG_PM_RUNTIME option was merged into CONFIG_PM a while ago, it removed this combination, of using CONFIG_PM_SLEEP without the earlier CONFIG_PM_RUNTIME. For this reason we can now rely on the subsystem/driver to use runtime PM to resume the device, instead of forcing that to be done in all cases. In other words, let's defer the runtime resume to a later point when it's actually needed.
