2017-08-31Input: xpad - fix PowerA init quirk for some gamepad modelsCameron Gutman
The PowerA gamepad initialization quirk worked with the PowerA wired gamepad I had around (0x24c6:0x543a), but a user reported [0] that it didn't work for him, even though our gamepads shared the same vendor and product IDs. When I initially implemented the PowerA quirk, I wanted to avoid actually triggering the rumble action during init. My tests showed that my gamepad would work correctly even if it received a rumble of 0 intensity, so that's what I went with. Unfortunately, this apparently isn't true for all models (perhaps a firmware difference?). This non-working gamepad seems to require the real magic rumble packet that the Microsoft driver sends, which actually vibrates the gamepad. To counteract this effect, I still send the old zero-rumble PowerA quirk packet which cancels the rumble effect before the motors can spin up enough to vibrate.

2017-08-31net_sched: add reverse binding for tc classCong Wang
TC filters when used as classifiers are bound to TC classes. However, there is a hidden difference when adding them in different orders: 1. If we add tc classes before its filters, everything is fine. Logically, the classes exist before we specify their ID's in filters, it is easy to bind them together, just as in the current code base. 2. If we add tc filters before the tc classes they bind, we have to do dynamic lookup in fast path. What's worse, this happens all the time not just once, because on fast path tcf_result is passed on stack, there is no way to propagate back to the one in tc filters. This hidden difference hurts performance silently if we have many tc classes in hierarchy. This patch intends to close this gap by doing the reverse binding when we create a new class, in this case we can actually search all the filters in its parent, match and fixup by classid. And because tcf_result is specific to each type of tc filter, we have to introduce a new ops for each filter to tell how to bind the class. Note, we still can NOT totally get rid of those class lookup in ->enqueue() because cgroup and flow filters have no way to determine the classid at setup time, they still have to go through dynamic lookup.

2017-08-31tty: goldfish: Use streaming DMA for r/w operations on Ranchu platformsMiodrag Dinic
Implement tty r/w operations using streaming DMA. Goldfish tty for Ranchu platforms has been modified to use streaming DMA mappings for read/write operations. This change eliminates the need for snooping through the TLB in QEMU using cpu_get_phys_page_debug() which does not guarantee that it will return the valid va -> pa mapping. The streaming DMA mapping is implemented using dma_map_single() per transfer, while dma_unmap_single() is used for unmapping right after the DMA transfer. Using DMA API is the proper way for handling r/w transfers and makes this driver more portable, thus effectively eliminating the need for virt_to_page() and page_to_phys() conversions. This change does not affect the old style Goldfish tty behaviour which is still used by the Goldfish emulator. Version register has been added and probed to see which platform is running this driver. Reading from the new register GOLDFISH_TTY_REG_VERSION using the Goldfish emulator will return 0 and driver will work with virtual addresses. Whereas if run on Ranchu it returns 1, and thus DMA is used. (Goldfish and Ranchu are code names for the first and the second generation of virtual boards used by Android emulator.)

2017-08-31eeprom: idt_89hpesx: Support both ACPI and OF probingHuy Duong
Allow the idt_89hpesx driver to get information from child nodes from both OF and ACPI by using more generic fwnode_property_read*() functions. Below is an example of instantiating idt_89hpesx driver via ACPI Table: Device(IDT0) { Name(_HID, "PRP0001") Name(_CID, "PRP0001") Name(_CCA, ONE) Name(_STR, Unicode("IDT SW I2C Slave")) Name(_CRS, ResourceTemplate () { I2cSerialBus (0x74, ControllerInitiated, 1000, AddressingMode7Bit, "\\_SB.I2CS", 0x00, ResourceConsumer, , ) }) Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () {"compatible", "idt,89hpes32nt8ag2"}, }, }) Device (EPR0) { Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () {"compatible", "onsemi,24c64"}, Package () {"reg", 0x50}, } }) } } Signed-off-by: Huy Duong <qhuyduong@hotmail.com> Acked-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-08-31mcb: Fix an error handling path in 'chameleon_parse_cells()'Christophe JAILLET
If 'chameleon_get_bar()' fails, we will return 0, which mean success. We should return the corresponding error code instead. Remove the useless initialisation of 'ret' which was hiding the issue. (if 'ret' is not set, gcc generates a warning ("warning: ‘ret’ may be used uninitialized in this function")) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

After switching to HR timers for RS485 the NULL checks for the object inside timer functions become useless. Remove them to avoid confusion to static analyzers.

2017-08-31earlycon: initialise baud field of earlycon device structureEugeniy Paltsev
For now baud field of earlycon structure device is't initialised at all in of_setup_earlycon (in oppositе to register_earlycon). So when I use stdout-path to point earlycon device (like stdout-path = &serial or stdout-path = "serial:115200n8") baud field of earlycon device structure remains uninitialised and earlycon initialization is not performed correctly as of_setup_earlycon is used. When pass all arguments via bootargs (like bootargs = "earlycon=uart8250,mmio32,0xf0005000,115200n8") initialization is performed correctly as register_earlycon is used. So initialise baud field of earlycon device structure by value of "current-speed" property from device tree or from options (if they exist) when we use of_setup_earlycon Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-08-31staging: r8822be: Simplify deinit_priv()Larry Finger
Now that the extraneous debugging code is removed, routine deinit_priv() clearly contains code that serves no useful purpose. A null test before a call to kfree() and a spurious cast are also removed.

2017-08-31staging: vboxvideo: Use CONFIG_DRM_KMS_FB_HELPER to check for fbdefio ↵Hans de Goede
availability Checking for CONFIG_FB_DEFERRED_IO is not the right thing to do since the fbdev code may be built as a module while vboxvideo is builtin. This can only happen when DRM_KMS_FB_HELPER is not set: a) DRM_VBOXVIDEO selects DRM_KMS_HELPER b) DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER c) DRM_KMS_FB_HELPER selects FB_DEFERRED_IO So when DRM_KMS_FB_HELPER is set and vboxvideo is builtin then FB_DEFERRED_IO must be builtin too. This commit moves the #ifdefs around fbdefio code over to CONFIG_DRM_KMS_FB_HELPER, as other drm drivers already do, fixing: drivers/staging/vboxvideo/vbox_fb.o: In function `vbox_fbdev_fini': vbox_fb.c:(.text+0x36): undefined reference to `fb_deferred_io_cleanup' Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
