2015-03-19usb: dwc2: avoid leaking DMA channels on disconnectionVincent Palatin
When the HCD is disconnected, the DMA transfers still in-flight were cleaned-up but the count of available DMA channels (e.g. available_host_channels) was not reset. The pool of DMA channels can be depleted when doing unclean disconnection of USB peripherals, and reaches the point where no transfer was possible until the next reboot/reload of the driver. Tested by putting a programmable USB mux on the port and randomly plugging/unpluging a USB HUB with USB mass-storage key, USB-audio and USB-ethernet dongle connected to its downstream ports, and also doing the disconnection early while the devices are still enumerating to get more URBs in-flight. After the patch, the devices are still enumerating after thousands of cycles, while the port was totally dead before.

2015-03-19selftests: Fix build failures when invoked from kselftest targetShuah Khan
Several tests that rely on implicit build rules fail to build, when invoked from the main Makefile kselftest target. These failures are due to --no-builtin-rules and --no-builtin-variables options set in the inherited MAKEFLAGS. --no-builtin-rules eliminates the use of built-in implicit rules and --no-builtin-variables is for not defining built-in variables. These two options override the use of implicit rules resulting in build failures. In addition, inherited LDFLAGS result in build failures and there is no need to define LDFLAGS. Clear LDFLAGS and MAKEFLAG when make is invoked from the main Makefile kselftest target. Fixing this at selftests Makefile avoids changing the main Makefile and keeps this change self contained at selftests level.

The socfpga.dtsi currently has the wrong interrupt number set for SPI master 1 Trying to use the master without this change results in the kernel boot process waiting forever for an interrupt that will never occur while attempting to probe any slave devices configured in the device tree as being under SPI master 1.

2015-03-19PCI: Assign resources before drivers claim devices (pci_scan_root_bus())Yijing Wang
Previously, pci_scan_root_bus() created a root PCI bus, enumerated the devices on it, and called pci_bus_add_devices(), which made the devices available for drivers to claim them. Most callers assigned resources to devices after pci_scan_root_bus() returns, which may be after drivers have claimed the devices. This is incorrect; the PCI core should not change device resources while a driver is managing the device. Remove pci_bus_add_devices() from pci_scan_root_bus() and do it after any resource assignment in the callers. Note that ARM's pci_common_init_dev() already called pci_bus_add_devices() after pci_scan_root_bus(), so we only need to remove the first call: pci_common_init_dev pcibios_init_hw pci_scan_root_bus pci_bus_add_devices # first call pci_bus_assign_resources pci_bus_add_devices # second call [bhelgaas: changelog, drop "root_bus" var in alpha common_init_pci(), return failure earlier in mn10300, add "return" in x86 pcibios_scan_root(), return early if xtensa platform_pcibios_fixup() fails] Signed-off-by: Yijing Wang <wangyijing@huawei.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> CC: Richard Henderson <rth@twiddle.net> CC: Ivan Kokshaysky <ink@jurassic.park.msu.ru> CC: Matt Turner <mattst88@gmail.com> CC: David Howells <dhowells@redhat.com> CC: Tony Luck <tony.luck@intel.com> CC: Michal Simek <monstr@monstr.eu> CC: Ralf Baechle <ralf@linux-mips.org> CC: Koichi Yasutake <yasutake.koichi@jp.panasonic.com> CC: Sebastian Ott <sebott@linux.vnet.ibm.com> CC: "David S.

2015-03-19fuse: explicitly set /dev/fuse file's private_dataTom Van Braeckel
The misc subsystem (which is used for /dev/fuse) initializes private_data to point to the misc device when a driver has registered a custom open file operation, and initializes it to NULL when a custom open file operation has *not* been provided. This subtle quirk is confusing, to the point where kernel code registers *empty* file open operations to have private_data point to the misc device structure. And it leads to bugs, where the addition or removal of a custom open file operation surprisingly changes the initial contents of a file's private_data structure. So to simplify things in the misc subsystem, a patch [1] has been proposed to *always* set the private_data to point to the misc device, instead of only doing this when a custom open file operation has been registered. But before this patch can be applied we need to modify drivers that make the assumption that a misc device file's private_data is initialized to NULL because they didn't register a custom open file operation, so they don't rely on this assumption anymore. FUSE uses private_data to store the fuse_conn and errors out if this is not initialized to NULL at mount time. Hence, we now set a file's private_data to NULL explicitly, to be independent of whatever value the misc subsystem initializes it to by default.

2015-03-19of: handle both '/' and ':' in path stringsBrian Norris
Commit 106937e8ccdc ("of: fix handling of '/' in options for of_find_node_by_path()") caused a regression in OF handling of stdout-path. While it fixes some cases which have '/' after the ':', it breaks cases where there is more than one '/' *before* the ':'. For example, it breaks this boot string stdout-path = "/rdb/serial@f040ab00:115200"; So rather than doing sequentialized checks (first for '/', then for ':'; or vice versa), to get the correct behavior we need to check for the first occurrence of either one of them. It so happens that the handy strcspn() helper can do just that.

2015-03-19of/irq: Fix of_irq_parse_one() returned error codesLaurent Pinchart

However, the error code variable res, which is initialized to -EINVAL when declared, is then overwritten with the return value of of_parse_phandle_with_args(), and reused as the return code from of_irq_parse_one().

2015-03-19iwlwifi: mvm: protect rate scaling against non-mvm IBSS stationsJohannes Berg
When the driver callback returns that it's out of space for new stations, the mac80211 IBSS code still keeps the station so it doesn't try to add it over and over again. Since the rate scaling algorithm is separate in mac80211, it also invokes the rate scaling algorithm for such stations. It doesn't know that our rate scaling algorithm is tightly integrated with the MVM code and relies on those data structures, and it cannot as the abstraction doesn't allow for it. This leads to crashes when the rate scaling algorithm tries to use uninitialized data, notably the mvmsta->vif pointer. Protect against this in the rate scaling algorithm. We cannot get good rates with such peers anyway since the firmware cannot do anything with them.

2015-03-19netfilter: restore rule tracing via nfnetlink_logPablo Neira Ayuso
Since fab4085 ("netfilter: log: nf_log_packet() as real unified interface"), the loginfo structure that is passed to nf_log_packet() is used to explicitly indicate the logger type you want to use. This is a problem for people tracing rules through nfnetlink_log since packets are always routed to the NF_LOG_TYPE logger after the aforementioned patch. We can fix this by removing the trace loginfo structures, but that still changes the log level from 4 to 5 for tracing messages and there may be someone relying on this outthere. So let's just introduce a new nf_log_trace() function that restores the former behaviour.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes Some urgent regression fixes to booting failures Exynos DRM occured. Summary: - Fix two urgent null pointer dereference bugs in case of enabling or disabling IOMMU. There was two cases to these issues. One is that plane->crtc is accessed by exynos_disable_plane() when device tree binding is broken so device driver tries to release, which means that the mode set operation isn't invoked yet so plane->crtc is still NULL and exynos_disable_plane() will access NULL pointer. This issue is fixed by checking if the plane->crtc is NULL or not in exynos_disable_plane() Other is that fimd_wait_for_vblank() is called to avoid from page fault with IOMMU before the ctx object is created. At this time, fimd_wait_for_vblank() tries to access ctx->crtc but the ctx->crtc is still NULL because exynos_drm_crtc_create() isn't called yet. This issue is fixed by creating a crtc object and setting it to ctx->crtc prior to fimd_wait_for_vblank() call.

Commit 7800064ba507 ("ARM: dts: Add basic dm816x device tree configuration") added basic devices for dm816x, but I was not able to test the GPIO interrupts earlier until I found some suitable pins to test with. We can mux the MMC card detect and write protect pins from SD_SDCD and SD_SDWP mode to use a normal GPIO interrupts that are also suitable for the MMC subsystem. This turned out several issues that need to be fixed: - I set the GPIO type wrong to be compatible with omap3 instead of omap4. The GPIO controller on dm816x has EOI interrupt register like omap4 and am335x. - I got the GPIO interrupt numbers wrong as each bank has two and we only use one. They need to be set up the same way as on am335x. - The gpio banks are missing interrupt controller related properties. With these changes the GPIO interrupts can be used with the MMC card detect pin, so let's wire that up. Let's also mux all the MMC lines for completeness while at it. For the first GPIO bank I tested using GPMC lines temporarily muxed to GPIOs on the dip switch 10.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound fixes from Takashi Iwai: "This is a collection of many small fixes. Most of fixes are for ASoC drivers, including the fixes of wrong field usages for boolean kctls. In addition, there is a fix in ASoC core for adding proper locks for component lists, and a fix for a HD-audio regression by the previous mono channel fix" * tag 'sound-4.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (24 commits) ALSA: hda - Treat stereo-to-mono mix properly ASoC: wm9713: Fix wrong value references for boolean kctl ASoC: wm9712: Fix wrong value references for boolean kctl ASoC: wm8960: Fix wrong value references for boolean kctl ASoC: wm8955: Fix wrong value references for boolean kctl ASoC: wm8904: Fix wrong value references for boolean kctl ASoC: wm8903: Fix wrong value references for boolean kctl ASoC: wm8731: Fix wrong value references for boolean kctl ASoC: wm2000: Fix wrong value references for boolean kctl ASoC: tas5086: Fix wrong value references for boolean kctl ASoC: pcm1681: Fix wrong value references for boolean kctl ASoC: es8238: Fix wrong value references for boolean kctl ASoC: cs4271: Fix wrong value references for boolean kctl ASoC: ak4641: Fix wrong value references for boolean kctl ASoC: adav80x: Fix wrong value references for boolean kctl ASoC: Fix component lists locking ASoC: Intel: remove conflicts when load/unload multiple firmware images ASoC: rt286: Change the DMI mapping for Dino ASoC: sgtl5000: remove useless register write clearing CHRGPUMP_POWERUP ASoC: fsl_ssi: Don't try to round-up for PM divisor calculation ...
