2013-01-14ALSA: usb-audio: correct M-Audio C400 clock source quirkEldad Zack
Taking another look at the C400 descriptors, I see now that there is a clock selector (0x80) for this device. Right now, the clock source points to the internal clock (0x81), which is also valid. When the external clock source (0x82) is selected in the mixer, and the rates mismatch (if it's free-running it is fixed to 48KHz), xruns will occur. Set the clock ID to the clock selector unit (0x81), which then allows the validation code to function correctly.

2013-01-14ALSA: usb - fix race in creation of M-Audio Fast track pro driverDavid Henningsson
A patch in the 3.2 kernel caused regression with hotplugging the M-Audio Fast track pro, or sound after suspend. I don't have the device so I haven't done a full analysis, but it seems userspace (both udev and pulseaudio) got confused when a card was created, immediately destroyed, and then created again. However, at least one person in the bug report (martin djfun) reports that this patch resolves the issue for him. It also leaves a message in the log: "snd-usb-audio: probe of 1-1.1:1.1 failed with error -5" which is a bit misleading. It is better than non-working audio, but maybe there's a more elegant solution?

2013-01-14udldrmfb: Fix EDID not working with monitors with EDID extension blocksHans de Goede
udldrmfb only reads the main EDID block, and if that advertises extensions the drm_edid code expects them to be present, and starts reading beyond the buffer udldrmfb passes it. Although it may be possible to read more EDID info with the udl we simpy don't know how, and even if trial and error gets it working on one device, that is no guarantee it will work on other revisions. So this patch does a simple fix in the form of patching the EDID info to report 0 extension blocks, this fixes udldrmfb only doing 1024x768 on monitors with EDID extension blocks.

2013-01-13drm/nvc0/fb: fix crash when different mutex is used to protect same listAleksi Torhamo
Fixes regression introduced in commit 861d2107 "drm/nouveau/fb: merge fb/vram and port to subdev interfaces" nv50_fb_vram_{new,del} functions were changed to use nouveau_subdev->mutex instead of the old nouveau_mm->mutex. nvc0_fb_vram_new still uses the nouveau_mm->mutex, but nvc0 doesn't have its own fb_vram_del function, using nv50_fb_vram_del instead. Because of this, on nvc0 a different mutex ends up being used to protect additions and deletions to the same list. This patch is a -stable candidate for 3.7.

Since nvc0_clock_pll_set is used for all PLLs, it has to specify which PLLs the code is used for, and only listed the first two VPLLs.

Since commit 5e120f6e4b3f35b741c5445dfc755f50128c3c44 "drm/nouveau/fence: convert to exec engine, and improve channel sync" nouveau fence sync implementation for nv17-50 and nvc0+ started to rely on state of fence buffer left by previous sync operation. But as pinned bo's (where fence state is stored) are not saved+restored across suspend/resume, we need to do it manually. nvc0+ was fixed by commit d6ba6d215a538a58f0f0026f0961b0b9125e8042 "drm/nvc0/fence: restore pre-suspend fence buffer context on resume".

2013-01-13drm/nouveau: fix blank LVDS screen regression on pre-nv50 cardsMarcin Slusarz
Commit 2a44e499 ("drm/nouveau/disp: introduce proper init/fini, separate from create/destroy") started to call display init routines on pre-nv50 hardware on module load. But LVDS init code sets driver state in a way which prevents modesetting code from operating properly. nv04_display_init calls nv04_dfp_restore, which sets encoder->last_dpms to NV_DPMS_CLEARED. drm_crtc_helper_set_mode nv04_dfp_prepare nv04_lvds_dpms(DRM_MODE_DPMS_OFF) nv04_lvds_dpms checks last_dpms mode (which is NV_DPMS_CLEARED) and wrongly assumes it's a "powersaving mode", the new one (DRM_MODE_DPMS_OFF) is too, so it skips calling some crucial lvds scripts.

2013-01-13drm/nouveau: do not forcibly power on lvds panelsBen Skeggs
This fix was put in place to fix a bug where the eDP panel on certain laptops fails to respond over the aux channel after suspend. It appears that on some systems (Dell M6600, with LVDS panel) there's a very bad interaction with the eDP init table that causes the SOR to get very confused and not drive the panel correctly, leading to bleed. A DPMS off/on cycle is enough to bring it back, but, this will avoid the problem by not touching the panel GPIOs at times we're not meant to. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-01-12be2net: fix unconditionally returning IRQ_HANDLED in INTxSathya Perla
commit e49cc34f introduced an unconditional IRQ_HANDLED return in be_intx() to workaround Lancer and BE2 HW issues. This is bad as it prevents the kernel from detecting interrupt storms due to broken HW. The BE2/Lancer HW issues are: 1) In Lancer, there is no means for the driver to detect if the interrupt belonged to device, other than counting and notifying events. 2) In Lancer de-asserting INTx takes a while, causing the INTx irq handler to be called multiple times till the de-assert happens. 3) In BE2, we see an occasional interrupt even when EQs are unarmed. Issue (1) can cause the notified events to be orphaned, if NAPI was already running. This patch fixes this issue by scheduling NAPI only if it is not scheduled already. Doing this also takes care of possible events_get() race that may be caused due to issue (2) and (3). Also, IRQ_HANDLED is returned only the first time zero events are detected.

Setting SDIS (Stream Disable Mode- bit 4 of USBMODE register) fixes the problem. However, in current code CI13XXX_DISABLE_STREAMING flag is only set in udc mode, so allow disabling streaming also in host mode. Tested on a mx6qsabrelite board.

2013-01-11USB: select USB_ARCH_HAS_EHCI for MXSMaxime Ripard
Commit 09f6ffde (USB: EHCI: fix build error by making ChipIdea host a normal EHCI driver) introduced a dependency on USB_EHCI_HCD for the chipidea USB host driver, that in turns depends on USB_ARCH_HAS_EHCI. If this symbol is not set for MXS, the MXS boards are not able to use the chipidea driver anymore.

2013-01-11net, wireless: overwrite default_ethtool_opsStanislaw Gruszka
Since: commit 2c60db037034d27f8c636403355d52872da92f81 Author: Eric Dumazet <edumazet@google.com> Date: Sun Sep 16 09:17:26 2012 +0000 net: provide a default dev->ethtool_ops wireless core does not correctly assign ethtool_ops. After alloc_netdev*() call, some cfg80211 drivers provide they own ethtool_ops, but some do not. For them, wireless core provide generic cfg80211_ethtool_ops, which is assigned in NETDEV_REGISTER notify call: if (!dev->ethtool_ops) dev->ethtool_ops = &cfg80211_ethtool_ops; But after Eric's commit, dev->ethtool_ops is no longer NULL (on cfg80211 drivers without custom ethtool_ops), but points to &default_ethtool_ops. In order to fix the problem, provide function which will overwrite default_ethtool_ops and use it by wireless core.
