2016-01-12ALSA: seq: Fix missing NULL check at remove_events ioctlTakashi Iwai
snd_seq_ioctl_remove_events() calls snd_seq_fifo_clear() unconditionally even if there is no FIFO assigned, and this leads to an Oops due to NULL dereference. The fix is just to add a proper NULL check.

2016-01-12ALSA: usb-audio: Avoid calling usb_autopm_put_interface() at disconnectTakashi Iwai
ALSA PCM may still have a leftover instance after disconnection and it delays its release. The problem is that the PCM close code path of USB-audio driver has a call of snd_usb_autosuspend(). This involves with the call of usb_autopm_put_interface() and it may lead to a kernel Oops due to the NULL object like: BUG: unable to handle kernel NULL pointer dereference at 0000000000000190 IP: [<ffffffff815ae7ef>] usb_autopm_put_interface+0xf/0x30 PGD 0 Call Trace: [<ffffffff8173bd94>] snd_usb_autosuspend+0x14/0x20 [<ffffffff817461bc>] snd_usb_pcm_close.isra.14+0x5c/0x90 [<ffffffff8174621f>] snd_usb_playback_close+0xf/0x20 [<ffffffff816ef58a>] snd_pcm_release_substream.part.36+0x3a/0x90 [<ffffffff816ef6b3>] snd_pcm_release+0xa3/0xb0 [<ffffffff816debb0>] snd_disconnect_release+0xd0/0xe0 [<ffffffff8114d417>] __fput+0x97/0x1d0 [<ffffffff8114d589>] ____fput+0x9/0x10 [<ffffffff8109e452>] task_work_run+0x72/0x90 [<ffffffff81088510>] do_exit+0x280/0xa80 [<ffffffff8108996a>] do_group_exit+0x3a/0xa0 [<ffffffff8109261f>] get_signal+0x1df/0x540 [<ffffffff81040903>] do_signal+0x23/0x620 [<ffffffff8114c128>] ? do_readv_writev+0x128/0x200 [<ffffffff810012e1>] prepare_exit_to_usermode+0x91/0xd0 [<ffffffff810013ba>] syscall_return_slowpath+0x9a/0x120 [<ffffffff817587cd>] ? __sys_recvmsg+0x5d/0x70 [<ffffffff810d2765>] ? ktime_get_ts64+0x45/0xe0 [<ffffffff8115dea0>] ?

ASoC: Updates for v4.5 This is quite a busy release on the driver front with a lot of new drivers being added but comparatively quiet on the core side with only one big change going in and that a fairly straightforward refactoring. - Conversion of the array of DAI links to a list by Mengdong Lin, supporting dynamically adding and removing DAI links. - Some more fixes for the topology code, though it is still not final and ready for enabling in production. We really need to get to the point where that can be done. - A pile of changes for Intel SkyLake drivers which hopefully deliver some useful initial functionality for systems with this chipset, though there is more work still to come. - New drivers for a number of Imagination Technologies IPs. - Lots of new features and cleanups for the Renesas drivers. - ANC support for WM5110. - New driver for Atmel class D speaker drivers. - New drivers for Cirrus CS47L24 and WM1831. - New driver for Dialog DA7128. - New drivers for Realtek RT5659 and RT56156. - New driver for Rockchip RK3036. - New driver for TI PC3168A # gpg: Signature made Wed 23 Dec 2015 00:42:40 GMT using RSA key ID 5D5487D0 # 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>" # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 3F25 68AA C269 98F9 E813 A1C5 C3F4 36CA 30F5 D8EB # Subkey fingerprint: ADE6 68AA 6757 18B5 9FE2 9FEA 24D6 8B72 5D54 87D0

2016-01-10ASoC: Make aux_dev more like a generic componentMengdong Lin
aux_dev is mainly used by the machine driver to specify analog devices, which are registered as codecs. Making it more like a generic component can help the machine driver to use it to specify any component with topology info by name. Details: - Remove the stub 'rtd_aux' array from the soc card. - Add a list 'aux_comp_list' to store the components of aux_devs. And add a list head 'list_aux' to struct snd_soc_component, for adding such components to the above list. - Add a 'init' ops to a component for machine specific init. soc_bind_aux_dev() will set it to be aux_dev's init. And it will be called when probing the component. - soc_bind_aux_dev() will also search components by name of an aux_dev, since it may not be a codec. - Move probing of aux_devs before checking new DAI links brought by topology. - Move removal of aux_devs later than removal of links. Because topology of aux components may register DAIs and the DAI drivers will go with removal of the aux components, we want soc_remove_link_dais() to remove the DAIs at first.
