rt286: add Thinkpad Helix 2 to force_combo_jack_table

2017-07-12T14:53:58+00:00

commit fe0dfd6358a17c79bd7d6996af7512ba452a7059 upstream. Thinkpad Helix 2 is a tablet PC, the audio is powered by Core M broadwell-audio and rt286 codec. For all versions of Linux kernel, the stereo output doesn't work properly when earphones are plugged in, the sound was coming out from both channels even if the audio contains only the left or right channel. Furthermore, if a music recorded in stereo is played, the two channels cancle out each other out, as a result, no voice but only distorted background music can be heard, like a sound card with builtin a Karaoke sount effect. Apparently this tablet uses a combo jack with polarity incorrectly set by rt286 driver. This patch adds DMI information of Thinkpad Helix 2 to force_combo_jack_table[] and the issue is resolved. The microphone input doesn't work regardless to the presence of this patch and still needs help from other developers to investigate. This is my first patch to LKML directly, sorry for CC-ing too many people here.

ASoC: Fix use-after-free at card unregistration

2017-06-14T13:07:49+00:00

commit 4efda5f2130da033aeedc5b3205569893b910de2 upstream. soc_cleanup_card_resources() call snd_card_free() at the last of its procedure. This turned out to lead to a use-after-free. PCM runtimes have been already removed via soc_remove_pcm_runtimes(), while it's dereferenced later in soc_pcm_free() called via snd_card_free(). The fix is simple: just move the snd_card_free() call to the beginning of the whole procedure. This also gives another benefit: it guarantees that all operations have been shut down before actually releasing the resources, which was racy until now.

commit 49b2e27ab9f66b0a22c21980ad8118a4038324ae upstream. During reset "refactoring" the output configuration was lost. This commit repairs sound on EDB93XX boards.

ASoC: Fixes for v4.11 A few last minute fixes for v4.11, the STI fix is relatively large but driver specific and has been cooking in -next for a little while now: - A fix from Takashi for some suspend/resume related crashes in the Intel drivers. - A fix from Mousumi Jana for issues with incorrectly created enumeration controls generated from topology files which could cause problems for userspace. - Fixes from Arnaud Pouliquen for some crashes due to races with the interrupt handler in the STI driver.

ASoC: intel: Fix PM and non-atomic crash in bytcr drivers

2017-04-25T14:54:30+00:00

The FE setups of Intel SST bytcr_rt5640 and bytcr_rt5651 drivers carry the ignore_suspend flag, and this prevents the suspend/resume working properly while the stream is running, since SST core code has the check of the running streams and returns -EBUSY. Drop these superfluous flags for fixing the behavior. Also, the bytcr_rt5640 driver lacks of nonatomic flag in some FE definitions, which leads to the kernel Oops at suspend/resume like: BUG: scheduling while atomic: systemd-sleep/3144/0x00000003 Call Trace: dump_stack+0x5c/0x7a __schedule_bug+0x55/0x70 __schedule+0x63c/0x8c0 schedule+0x3d/0x90 schedule_timeout+0x16b/0x320 ? del_timer_sync+0x50/0x50 ? sst_wait_timeout+0xa9/0x170 [snd_intel_sst_core] ? sst_wait_timeout+0xa9/0x170 [snd_intel_sst_core] ? remove_wait_queue+0x60/0x60 ? sst_prepare_and_post_msg+0x275/0x960 [snd_intel_sst_core] ? sst_pause_stream+0x9b/0x110 [snd_intel_sst_core] ....

ASoC: STI: Fix null ptr deference in IRQ handler

2017-04-06T18:29:07+00:00

With RTlinux a race condition has been found that leads to NULL ptr crash: - On CPU 0: uni_player_irq_handler is called to treat XRUN "(player->state == UNIPERIF_STATE_STOPPED)" is FALSE so status is checked, dev_err(player->dev, "FIFO underflow error detected") is printed and then snd_pcm_stream_lock should be called to lock stream for stopping. - On CPU 1: application stop and close the stream. Issue is that the stop and shutdown functions are executed while "FIFO underflow error detected" is printed. So when CPU 0 calls snd_pcm_stream_lock, player->substream is already null.

2017-03-30T18:03:25+00:00

ASoC: Fixes for v4.11 A relatively large pile of fixes for mainline, the first since the merge window. The biggest block of changes here by volume is the sun8i-codec set, the driver was newly added in the merge window but it was realized that renaming some of the user visible controls was required so these are being pushed for v4.11 to avoid the original code appearing in a release. Otherwise it's all fairly standard bugfix stuff.
