2016-04-01ALSA: timer: Use mod_timer() for rearming the system timerTakashi Iwai
ALSA system timer backend stops the timer via del_timer() without sync and leaves del_timer_sync() at the close instead. This is because of the restriction by the design of ALSA timer: namely, the stop callback may be called from the timer handler, and calling the sync shall lead to a hangup. However, this also triggers a kernel BUG() when the timer is rearmed immediately after stopping without sync: kernel BUG at kernel/time/timer.c:966! Call Trace: <IRQ> [<ffffffff8239c94e>] snd_timer_s_start+0x13e/0x1a0 [<ffffffff8239e1f4>] snd_timer_interrupt+0x504/0xec0 [<ffffffff8122fca0>] ? debug_check_no_locks_freed+0x290/0x290 [<ffffffff8239ec64>] snd_timer_s_function+0xb4/0x120 [<ffffffff81296b72>] call_timer_fn+0x162/0x520 [<ffffffff81296add>] ? call_timer_fn+0xcd/0x520 [<ffffffff8239ebb0>] ? snd_timer_interrupt+0xec0/0xec0 .... It's the place where add_timer() checks the pending timer. It's clear that this may happen after the immediate restart without sync in our cases. So, the workaround here is just to use mod_timer() instead of add_timer(). This looks like a band-aid fix, but it's a right move, as snd_timer_interrupt() takes care of the continuous rearm of timer.

2016-03-31ALSA: usb-audio: Fix double-free in error paths after ↵Vladis Dronov
snd_usb_add_audio_stream() call create_fixed_stream_quirk(), snd_usb_parse_audio_interface() and create_uaxx_quirk() functions allocate the audioformat object by themselves and free it upon error before returning. However, once the object is linked to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be double-freed, eventually resulting in a memory corruption. This patch fixes these failures in the error paths by unlinking the audioformat object before freeing it.

2016-03-20ALSA: hda - Workaround for unbalanced i915 power refcount by concurrent probeTakashi Iwai
The recent addition of on-demand i915 audio component binding in the codec driver seems leading to the unbalanced i915 power refcount, according to Intel CI tests. Typically, it gets a kernel WARNING like: WARNING: CPU: 3 PID: 173 at sound/hda/hdac_i915.c:91 snd_hdac_display_power+0xf1/0x110 [snd_hda_core]() Call Trace: [<ffffffff813fef15>] dump_stack+0x67/0x92 [<ffffffff81078a21>] warn_slowpath_common+0x81/0xc0 [<ffffffff81078b15>] warn_slowpath_null+0x15/0x20 [<ffffffffa00f77e1>] snd_hdac_display_power+0xf1/0x110 [snd_hda_core] [<ffffffffa015039d>] azx_intel_link_power+0xd/0x10 [snd_hda_intel] [<ffffffffa011e32a>] azx_link_power+0x1a/0x30 [snd_hda_codec] [<ffffffffa00f21f9>] snd_hdac_link_power+0x29/0x40 [snd_hda_core] [<ffffffffa01192a6>] hda_codec_runtime_suspend+0x76/0xa0 [snd_hda_codec] ..... The scenario is like below: - HD-audio driver and i915 driver are probed concurrently at the (almost) same time; HDA bus tries to bind with i915, but it fails because i915 initialization is still being processed. - Later on, HD-audio probes the HDMI codec, where it again tries to bind with i915. At this time, it succeeds. - At finishing the probe of HDA, it decreases the refcount as if it were already bound at the bus probe, since the component is bound now. This triggers a kernel WARNING due to the unbalance. As a workaround, in this patch, we just disable the on-demand i915 component binding in the codec driver. This essentially reverts back to the state of 4.4 kernel. We know that this is no real solution, but it's a minimalistic simple change that can be applied to 4.5.x kernel as stable.

2016-03-18ALSA: hda - Fix spurious kernel WARNING on Baytrail HDMITakashi Iwai
snd_hdac_sync_audio_rate() call is mandatory only for HSW and later models, but we call the function unconditionally blindly assuming that the function doesn't do anything harmful. But since recently, the function checks the validity of the passed pin NID, and eventually spews the warning if an unexpected pin is passed. This is seen on old chips like Baytrail. The fix is to limit the call of this function again only for the chips with the proper binding. This can be identified by the same flag as the eld notifier.

2016-03-18ALSA: hda - Really restrict i915 notifier to HSW+Takashi Iwai
The commit [b62232d429fa: ALSA: hda - Limit i915 HDMI binding only for HSW and later] tried to limit the usage of i915 audio notifier to the recent Intel models and switch to the old method on pre-Haswell models. However, it assumed that the i915 component binding hasn't been done on such models, and the assumption was wrong: namely, Baytrail had already the i915 component binding due to powerwell control. Thus, the workaround wasn't applied to Baytrail. For fixing this properly, this patch introduces a new flag indicating the usage of audio notifier and codec_has_acomp() refers to this flag instead of checking the existence of audio component.

2016-03-17ALSA: hda - Fix mutex deadlock at HDMI/DP hotplugTakashi Iwai
The recent change in HD-audio HDMI/DP codec driver for allowing the dynamic PCM binding introduced a new spec->pcm_mutex. One of the protected area by this mutex is hdmi_present_sense(). As reported by Intel CI tests, unfortunately, the new mutex causes a deadlock when the hotplug/unplug is triggered during the codec is in runtime suspend. The buggy code path is like the following: hdmi_unsol_event() -> ... -> hdmi_present_sense() ==> ** here taking pcm_mutex -> hdmi_present_sense_via_verbs() -> snd_hda_power_up_pm() -> ... (runtime resume calls) -> generic_hdmi_resume() -> hdmi_present_sense() ==> ** here taking pcm_mutex again! As we can see here, the problem is that the mutex is taken before snd_hda_power_up_pm() call that triggers the runtime resume. That is, the obvious solution is to move the power up/down call outside the mutex; it is exactly what this patch provides. The patch also clarifies why this bug wasn't caught beforehand. We used to have the i915 audio component for hotplug for all Intel chips, and in that code path, there is no power up required but the information is taken directly from the graphics side. However, we recently switched back to the old method for some old Intel chips due to regressions, and now the deadlock issue is surfaced.

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.

2016-03-15ALSA: hda - Limit i915 HDMI binding only for HSW and laterTakashi Iwai
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.

2016-03-15ALSA: hda - Fix unconditional GPIO toggle via automuteTakashi Iwai
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.

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.
