ASoC: qcom: Drop HAS_DMA dependency to fix link failure

2020-07-29T08:16:58+00:00

commit b6aa06de7757667bac88997a8807b143b8436035 upstream. When building on allyesconfig kernel for a NO_DMA=y platform (e.g. Sun-3), CONFIG_SND_SOC_QCOM_COMMON=y, but CONFIG_SND_SOC_QDSP6_AFE=n, leading to a link failure: sound/soc/qcom/common.o: In function `qcom_snd_parse_of': common.c:(.text+0x2e2): undefined reference to `q6afe_is_rx_port' While SND_SOC_QDSP6 depends on HAS_DMA, SND_SOC_MSM8996 and SND_SOC_SDM845 don't, so the following warning is seen: WARNING: unmet direct dependencies detected for SND_SOC_QDSP6 Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && QCOM_APR [=y] && HAS_DMA [=n] Selected by [y]: - SND_SOC_MSM8996 [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && QCOM_APR [=y] - SND_SOC_SDM845 [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && QCOM_APR [=y] && CROS_EC [=y] && I2C [=y] && SOUNDWIRE [=y] Until recently, this warning was harmless (from a compile-testing point-of-view), but the new user of q6afe_is_rx_port() turned this into a hard failure. As the QDSP6 driver itself builds fine if NO_DMA=y, and it depends on QCOM_APR (which in turns depends on ARCH_QCOM || COMPILE_TEST), it is safe to increase compile testing coverage. Hence fix the link failure by dropping the HAS_DMA dependency of SND_SOC_QDSP6.

ASoC: rt5670: Add new gpio1_is_ext_spk_en quirk and enable it on the Lenovo Miix 2 10

2020-07-29T08:16:58+00:00

commit 85ca6b17e2bb96b19caac3b02c003d670b66de96 upstream. The Lenovo Miix 2 10 has a keyboard dock with extra speakers in the dock. Rather then the ACL5672's GPIO1 pin being used as IRQ to the CPU, it is actually used to enable the amplifier for these speakers (the IRQ to the CPU comes directly from the jack-detect switch). Add a quirk for having an ext speaker-amplifier enable pin on GPIO1 and replace the Lenovo Miix 2 10's dmi_system_id table entry's wrong GPIO_DEV quirk (which needs to be renamed to GPIO1_IS_IRQ) with the new RT5670_GPIO1_IS_EXT_SPK_EN quirk, so that we enable the external speaker-amplifier as necessary. Also update the ident field for the dmi_system_id table entry, the Miix models are not Thinkpads.

ASoC: rt5670: Correct RT5670_LDO_SEL_MASK

2020-07-29T08:16:47+00:00

commit 5cacc6f5764e94fa753b2c1f5f7f1f3f74286e82 upstream. The RT5670_PWR_ANLG1 register has 3 bits to select the LDO voltage, so the correct mask is 0x7 not 0x3. Because of this wrong mask we were programming the ldo bits to a setting of binary 001 (0x05 & 0x03) instead of binary 101 when moving to SND_SOC_BIAS_PREPARE. According to the datasheet 001 is a reserved value, so no idea what it did, since the driver was working fine before I guess we got lucky and it does something which is ok.

ALSA: info: Drop WARN_ON() from buffer NULL sanity check

2020-07-29T08:16:47+00:00

commit 60379ba08532eca861e933b389526a4dc89e0c42 upstream. snd_info_get_line() has a sanity check of NULL buffer -- both buffer itself being NULL and buffer->buffer being NULL. Basically both checks are valid and necessary, but the problem is that it's with snd_BUG_ON() macro that triggers WARN_ON(). The latter condition (NULL buffer->buffer) can be met arbitrarily by user since the buffer is allocated at the first write, so it means that user can trigger WARN_ON() at will. This patch addresses it by simply moving buffer->buffer NULL check out of snd_BUG_ON() so that spurious WARNING is no longer triggered.

ALSA: usb-audio: Fix race against the error recovery URB submission

2020-07-22T07:32:08+00:00

commit 9b7e5208a941e2e491a83eb5fa83d889e888fa2f upstream. USB MIDI driver has an error recovery mechanism to resubmit the URB in the delayed timer handler, and this may race with the standard start / stop operations. Although both start and stop operations themselves don't race with each other due to the umidi->mutex protection, but this isn't applied to the timer handler. For fixing this potential race, the following changes are applied: - Since the timer handler can't use the mutex, we apply the umidi->disc_lock protection at each input stream URB submission; this also needs to change the GFP flag to GFP_ATOMIC - Add a check of the URB refcount and skip if already submitted - Move the timer cancel call at disconnection to the beginning of the procedure; this assures the in-flight timer handler is gone properly before killing all pending URBs Reported-by: syzbot+0f4ecfe6a2c322c81728@syzkaller.appspotmail.com Reported-by: syzbot+5f1d24c49c1d2c427497@syzkaller.appspotmail.com Cc: Link: https://lore.kernel.org/r/20200710160656.16819-1-tiwai@suse.de Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman

ALSA: line6: Sync the pending work cancel at disconnection

commit 68359a1ad8447c99732ebeab8c169bfed543667a upstream. Recently syzkaller reported a UAF in LINE6 driver, and it's likely because we call cancel_delayed_work() at the disconnect callback instead of cancel_delayed_work_sync(). Let's use the correct one instead.

ALSA: line6: Perform sanity check for each URB creation

commit 6e8a914ad619042c5f25a4feb663357c4170fd8d upstream. LINE6 drivers create stream URBs with a fixed pipe without checking its validity, and this may lead to a kernel WARNING at the submission when a malformed USB descriptor is passed. For avoiding the kernel warning, perform the similar sanity checks for each pipe type at creating a URB.

This patch delays the registration until the second interface appears.
