2013-06-28genirq: Fix can_request_irq() for IRQs without an actionBen Hutchings
Commit 02725e7471b8 ('genirq: Use irq_get/put functions'), inadvertently changed can_request_irq() to return 0 for IRQs that have no action. This causes pcibios_lookup_irq() to select only IRQs that already have an action with IRQF_SHARED set, or to fail if there are none. Change can_request_irq() to return 1 for IRQs that have no action (if the first two conditions are met).

Commit 9ddec56131 (cifs: move handling of signed connections into separate function) broke signing on SMB2/3 connections. While the code to enable signing on the connections was very similar between the two, the bits that get set in the sec_mode are different. Declare a couple of new smb_version_values fields and set them appropriately for SMB1 and SMB2/3. Then change cifs_enable_signing to use those instead.

2013-06-27cgroup: CGRP_ROOT_SUBSYS_BOUND should be ignored when comparing mount optionsTejun Heo
1672d04070 ("cgroup: fix cgroupfs_root early destruction path") introduced CGRP_ROOT_SUBSYS_BOUND which is used to mark completion of subsys binding on a new root; however, this broke remounts. cgroup_remount() doesn't allow changing root options via remount and CGRP_ROOT_SUBSYS_BOUND, which is set on all fully initialized roots, makes the function reject all remounts. Fix it by putting the options part in the lower 16 bits of root->flags and masking the comparions. While at it, make cgroup_remount() emit an error message explaining why it's rejecting a remount request, so that it's less of a mystery. Signed-off-by: Tejun Heo <tj@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/late From David Brown: MSM clock updates for 3.11. Per Stephen Boyd's coverletter: Resending to collect higher level maintainer acks per Olof's request. The plan is to push this patchset through MSM to the arm-soc tree. This patchset moves the existing MSM clock code and affected drivers to the common clock framework. A prerequisite of moving to the common clock framework is to use clk_prepare() and clk_enable() so the first few patches migrate drivers to that call (clk_prepare() is a no-op on MSM right now). It also removes some custom clock APIs that MSM provides and finally moves the proc_comm clock code to the common struct clk. This patch series will be used as the foundation of the MSM 8660/8960 clock code that I plan to send out after this series. * tag 'msm-clock-for-3.11b' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm: ARM: msm: Migrate to common clock framework ARM: msm: Make proc_comm clock control into a platform driver ARM: msm: Prepare clk_get() users in mach-msm for clock-pcom driver ARM: msm: Remove clock-7x30.h include file ARM: msm: Remove custom clk_set_{max,min}_rate() API ARM: msm: Remove custom clk_set_flags() API msm: iommu: Use clk_set_rate() instead of clk_set_min_rate() msm: iommu: Convert to clk_prepare/unprepare msm_sdcc: Convert to clk_prepare/unprepare usb: otg: msm: Convert to clk_prepare/unprepare msm_serial: Use devm_clk_get() and properly return errors msm_serial: Convert to clk_prepare/unprepare Acked-by: Chris Ball <cjb@laptop.org> # for msm_sdcc.c Signed-off-by: Olof Johansson <olof@lixom.net>

2013-06-27PM / Sleep: Warn about system time after resume with pm_traceShuah Khan
pm_trace uses the system's Real Time Clock (RTC) to save the magic number. The reason for this is that the RTC is the only reliably available piece of hardware during resume operations where a value can be set that will survive a reboot. Consequence is that after a resume (even if it is successful) your system clock will have a value corresponding to the magic number instead of the correct date/time! It is therefore advisable to use a program like ntp-date or rdate to reset the correct date/time from an external time source when using this trace option. There is no run-time message to warn users of the consequences of enabling pm_trace. Adding a warning message to pm_trace_store() will serve as a reminder to users to set the system date and time after resume.

2013-06-27ALSA: usb-audio: claim autodetected PCM interfaces all at onceClemens Ladisch
snd_card_register() registers all devices newly added since the last call. However, the playback/capture streams are handled as one ALSA device, so the second /dev device will not be registered if the PCM streams are added in two steps. QUIRK_AUTODETECT caused the probe callback to be called once for each interface, which triggered this problem. Work around this by handling this like the composite quirk, i.e., autodetecting all other interfaces that might be used for PCM or MIDI. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2013-06-27ALSA: usb-audio: add support for many Roland/Yamaha devicesClemens Ladisch
Add quirks to detect the various vendor-specific descriptors used by Roland and Yamaha in most of their recent USB audio and MIDI devices. Together with the previous patch, this should add audio/MIDI support for the following USB devices: - Edirol motion dive .tokyo performance package - Roland MC-808 Synthesizer - Roland BK-7m Synthesizer - Roland VIMA JM-5/8 Synthesizer - Roland SP-555 Sequencer - Roland V-Synth GT Synthesizer - Roland Music Atelier AT-75/100/300/350C/500/800/900/900C Organ - Edirol V-Mixer M-200i/300/380/400/480/R-1000 - BOSS GT-10B Effects Processor - Roland Fantom G6/G7/G8 Keyboard - Cakewalk Sonar V-Studio 20/100/700 Audio Interface - Roland GW-8 Keyboard - Roland AX-Synth Keyboard - Roland JUNO-Di/STAGE/Gi Keyboard - Roland VB-99 Effects Processor - Cakewalk UM-2G MIDI Interface - Roland A-500S Keyboard - Roland SD-50 Synthesizer - Roland OCTAPAD SPD-30 Controller - Roland Lucina AX-09 Synthesizer - BOSS BR-800 Digital Recorder - Roland DUO/TRI-CAPTURE (EX) Audio Interface - BOSS RC-300 Loop Station - Roland JUPITER-50/80 Keyboard - Roland R-26 Recorder - Roland SPD-SX Controller - BOSS JS-10 Audio Player - Roland TD-11/15/30 Drum Module - Roland A-49/88 Keyboard - Roland INTEGRA-7 Synthesizer - Roland R-88 Recorder Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-06-27ALSA: usb-audio: detect implicit feedback on Roland devicesClemens Ladisch
All the Roland/Edirol/BOSS USB audio devices that need implicit feedback show this unambiguously in their descriptors, so it might be a good idea to let the driver detect this. This should make playback work correctly (at least with Jack) with the following devices: - BOSS GT-100 - BOSS JS-8 Jam Station - Edirol M-16DX - Roland GAIA SH-01 Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-06-27ALSA: usb-audio: store protocol version in struct audioformatClemens Ladisch
Instead of reading bInterfaceProtocol from the descriptor whenever it's needed, store this value in the audioformat structure. Besides simplifying some code, this will allow us to correctly handle vendor- specific devices where the descriptors are marked with other values. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
