[PATCH] drm/meson: Enable fast_io in meson_dw_hdmi_regmap_config

by Lyude Paul

Seeing as we use this registermap in the context of our IRQ handlers, we need to be using spinlocks for reading/writing registers so that we can still read them from IRQ handlers without having to grab any mutexes and accidentally sleep. We don't currently do this, as pointed out by lockdep: [ 18.403770] BUG: sleeping function called from invalid context at kernel/locking/mutex.c:908 [ 18.406744] in_atomic(): 1, irqs_disabled(): 128, pid: 68, name: kworker/u17:0 [ 18.413864] INFO: lockdep is turned off.

[PATCH] ALSA: hda/realtek - fix the pop noise on headphone for lenovo laptops

by Hui Wang

We have several Lenovo laptops with the codec alc285, when playing sound via headphone, we can hear click/pop noise in the headphone, if we let the headphone share the DAC of NID 0x2 with the speaker, the noise disappears. The Lenovo laptops here include P52, P72, X1 yoda2 and X1 carbon. I have tried to set preferred_dacs and override_conn, but neither of them worked. Thanks for Kailang, he told me to invalidate the NID 0x3 through override_wcaps.

[PATCH v3.16 1/2] v4l: event: Prevent freeing event subscriptions while accessed

by Sakari Ailus

[ upstream commit ad608fbcf166fec809e402d548761768f602702c ] The event subscriptions are added to the subscribed event list while holding a spinlock, but that lock is subsequently released while still accessing the subscription object. This makes it possible to unsubscribe the event --- and freeing the subscription object's memory --- while the subscription object is simultaneously accessed. Prevent this by adding a mutex to serialise the event subscription and unsubscription. This also gives a guarantee to the callback ops that the add op has returned before the del op is called. This change also results in making the elems field less special: subscriptions are only added to the event list once they are fully initialised.

[PATCH v4.4 1/1] v4l: event: Add subscription to list before calling "add" operation

by Sakari Ailus

[ upstream commit 92539d3eda2c090b382699bbb896d4b54e9bdece ] Patch ad608fbcf166 changed how events were subscribed to address an issue elsewhere. As a side effect of that change, the "add" callback was called before the event subscription was added to the list of subscribed events, causing the first event queued by the add callback (and possibly other events arriving soon afterwards) to be lost. Fix this by adding the subscription to the list before calling the "add" callback, and clean up afterwards if that fails.

patch "usb: core: quirks: add RESET_RESUME quirk for Cherry G230 Stream" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: core: quirks: add RESET_RESUME quirk for Cherry G230 Stream to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From effd14f66cc1ef6701a19c5a56e39c35f4d395a5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michael=20Niew=C3=B6hner?= <linux(a)mniewoehner.de> Date: Sun, 25 Nov 2018 17:57:33 +0100 Subject: usb: core: quirks: add RESET_RESUME quirk for Cherry G230 Stream series MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cherry G230 Stream 2.0 (G85-231) and 3.0 (G85-232) need this quirk to function correctly.
