Add some sanity check codes before actually accessing the endpoint via get_endpoint() in order to avoid the invalid access through a malformed USB descriptor. Mostly just checking bNumEndpoints, but in one place (snd_microii_spdif_default_get()), the validity of iface and altsetting index is checked as well.

create_fixed_stream_quirk() may cause a NULL-pointer dereference by accessing the non-existing endpoint when a USB device with a malformed USB descriptor is used. This patch avoids it simply by adding a sanity check of bNumEndpoints before the accesses.

It turned out that the pre-HSW Intel chips are incompatible with the naive assumption we had -- the fixed mapping between the port and the HD-audio widget. This may result in the bad access, as captured by the recent patch to add a WARN_ON() for the port mapping check. As a quick workaround, disable the i915 audio component binding for all pre-Haswell models.

Cirrus HD-audio driver may adjust GPIO pins for EAPD dynamically depending on the jack plug state. This works fine for the auto-mute mode where the speaker gets muted upon the HP jack plug. OTOH, when the auto-mute mode is off, this turns off the EAPD unexpectedly depending on the jack state, which results in the silent speaker output. This patch fixes the silent speaker output issue by setting GPIO bits constantly when the auto-mute mode is off.

ASoC: Updates for v4.6 The main thing in terms of the core this time around has been some additional framework work for dynamic topologies (though we *still* don't appear to have a stable ABI for the topology code, it's probably worth considering if this will ever happen...). Otherwise the work has almost all been in the drivers: - HDMI support for Sky Lake, along with other fixes and enhancements for the Intel drivers. - Lots of improvements to the Renesas drivers. - Capture support for Qualcomm drivers. - Support for TI DaVinci DRA7xxx devices. - New machine drivers for Freescale systems with Cirrus CODECs, Mediatek systems with RT5650 CODECs. - New CPU drivers for Allwinner S/PDIF controllers - New CODEC drivers for Maxim MAX9867 and MAX98926 and Realtek RT5514.

nvhdmi_chmap_cea_alloc_validate_get_type calls itself recursively using chmap ops causing the double fault.

ASoC: Fixes for v4.5 This is far too big a set of fixes for this late in the release cycle but the overwhelming bulk is essentially the same simple fix from Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace interface where drivers were accessing things using the wrong element in a union which worked OK on 32 bit platforms as the correct element happened to be aligned the same way but with 64 bit platforms ABIs are different and the two members of the union are laid out in different places. They aren't all tagged to stable since some of these chips have vanishingly little chance of being used in 64 bit systems. The other changes are: - A fix for Qualcomm devices to work on big endian systems. The original change is actually correct but triggered a bug in regmap which is too invasive to fix for this cycle and can be worked around by just letting regmap pick the default. - A fix for the Samsung I2S driver locking which wasn't using IRQ safe spinlocks when it needed to. - A fix for the new Intel Sky Lake driver forgetting that C pointer arithmetic takes the type of the pointer into consideration. - A revert of a change to the FSL SSI driver that broke some systems. - A fix for the cleanup path of the wm9713 driver. - A fix for some incorrect register definitions in the ADAU17x1 driver that caused misclocking in some configurations. - A fix for the tracepoints for jack detection to avoid using an internal field of the core jack structure which is no longer present in all configurations. - A fix for another of the new Intel drivers which tried to write to a string literal. # gpg: Signature made Mon 07 Mar 2016 09:41:48 ICT using RSA key ID 5D5487D0 # gpg: key CD7BEEBC: no public key for trusted key - skipped # gpg: key CD7BEEBC marked as ultimately trusted # gpg: key AF88CD16: no public key for trusted key - skipped # gpg: key AF88CD16 marked as ultimately trusted # gpg: key 16005C11: no public key for trusted key - skipped # gpg: key 16005C11 marked as ultimately trusted # gpg: key 5621E907: no public key for trusted key - skipped # gpg: key 5621E907 marked as ultimately trusted # gpg: key 5C6153AD: no public key for trusted key - skipped # gpg: key 5C6153AD marked as ultimately trusted # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>"

Renesas sound driver user needs to read its datasheet when create DT. But it is difficult to understand, because it has many modules (SRC/CTU/MIX/DVC/SSIU/SSI/AudioDMAC/AudioDMACperiperi), and many features (Asynchronous/Synchronous mode on SRC, CTU matrix, DVC volume settings feature, Multi-SSI/TDM-SSI, etc). This patch adds simplified explanation to help setting/understanding. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
