git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"No surprises in this development cycle, and most of work is about the
fixes and the improvements of the existing code, while a new LED
control layer and a few new drivers have been introduced.
Here are some highlights:
Core:
- A common mute-LED framework was introduced. It is used by HD-audio
for now, more adaption will follow later. The former "Mic Mute-LED
Mode" mixer control has been replaced with the corresponding sysfs
now.
- User-control management was changed to count consumed bytes instead
of capping by number of elements; this will allow more controls in
the normal usage pattern while avoiding the possible memory
exhaustion DoS
ASoC:
- Continued refactoring and cleanups in ASoC core and generic card
drivers
- Wide range of small cppcheck and warning fixes
- New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
accessory detection, and Realtek RT1019, RT1316, RT711 and RT715
USB-audio:
- Continued improvements and fixes of the implicit feedback mode,
including better support for Pioneer and Roland/BOSS devices
HD-audio:
- Default back to non-buffer preallocation on x86
- Cirrus codec improvements, more quirks for Realtek codecs
Others:
- New virtio sound driver
- FireWire Bebob updates"

0d5370d1d852 ("PCI: Prevent VPD access for QLogic ISP2722") disabled access
to VPD of the ISP2722-based 16/32Gb Fibre Channel to PCIe Adapter because
reading past the end of the VPD caused NMIs.
104daa71b396 ("PCI: Determine actual VPD size on first access") limits
reads to the actual size of VPD, which should prevent these NMIs.
104daa71b396 was merged *before* 0d5370d1d852, but we think the testing
that prompted 0d5370d1d852 ("PCI: Prevent VPD access for QLogic ISP2722")
was done with a kernel that lacked 104daa71b396. See [1, 2].
Remove the quirk added by 0d5370d1d852 ("PCI: Prevent VPD access for QLogic
ISP2722") so customers can read the HBA VPD.

Realtek RTL8169/8168/8125 NIC families indicate VPD capability and an
optional VPD EEPROM can be connected via I2C/SPI. However I haven't seen
any card or system with such a VPD EEPROM yet. The missing EEPROM causes
the following warning whenever e.g. lscpi -vv is executed.
invalid short VPD tag 00 at offset 01
The warning confuses users, and I think we should handle the situation more
gently. Therefore, if first VPD byte is read as 0x00, assume a missing
optional VPD PROM and replace the warning with a more descriptive message
at info level.

24a1720a0841 ("cxgb4: collect serial config version from register") removed
the only usage of pci_set_vpd_size(). If a device needs to override the
auto-detected VPD size, then this can be done with a PCI quirk, as is done
for Chelsio devices. There's no need to allow drivers to change the VPD
size.
Remove pci_set_vpd_size().

remap_io_sg claims that the pgprot is pre-verified using an io_mapping,
but actually does not get passed an io_mapping and just uses the pgprot in
the VMA. Remove the apply_to_page_range abuse and just loop over
remap_pfn_range for each segment.
Note: this could use io_mapping_map_user by passing an iomap to
remap_io_sg if the maintainers can verify that the pgprot in the iomap in
the only caller is indeed the desired one here.

Kernel panic - not syncing: Fatal exception: panic_on_oops
When allocation/initialization of the blk_mq_tag_set fails in
dm_mq_init_request_queue(), it is uninitialized/freed, but the pointer
is not reset to NULL; so when dev_remove() later gets into
dm_mq_cleanup_mapped_device() it sees the pointer and tries to
uninitialize and free it again.
Fix this by setting the pointer to NULL in dm_mq_init_request_queue()
error-handling. Also set it to NULL in dm_mq_cleanup_mapped_device().

The condition to check the cdev pointer validity on
css_sch_device_unregister() is a leftover from the 'commit 8cc0dcfdc1c0
("s390/cio: remove pm support from ccw bus driver")'. This could lead to a
situation, where detaching the device is not happening completely. Remove
this invalid condition in the IO_SCH_UNREG case.

With zpci_configure_device() now always called on a device that has
already been configured on the platform level its name has become
misleading. Rename it to zpci_scan_configured_device() to signify that
the function now only handles the correct scanning of a newly configured
PCI function taking care of the special handling necessary for function
0 and functions parked waiting for a PCI bus that can't be created
without first seeing function 0.

drm/tegra: Changes for v5.13-rc1
The changes this time around contain a couple of fixes for host1x along
with some improvements for Tegra DRM. Most notably the Tegra DRM driver
now supports the hardware cursor on Tegra186 and later, more correctly
reflects the capabilities of the display pipelines on various Tegra SoC
generations and knows how to deal with the dGPU sector layout by using
framebuffer modifiers.

The RTC_OSC_REG register is 32-bit, but the useful information is found
in the 7 least significant bits (bits 7-31 are reserved). And in fact,
as you can see from the code, all read accesses are 8-bit, as well as
some writes. Let's make sure all writes are 8-bit. Moreover, in contexts
where consecutive reads / writes after the busy check must take place
within 15 us, it is better not to waste time on useless accesses.

Now that the core is aware of whether alarms are available, it is possible
to decide whether UIE emulation is required before actually trying to set
the alarm.
This greatly simplifies rtc_update_irq_enable because there is now only one
error value to track and is not relying on the return value of
__rtc_set_alarm anymore.
