+Subject: ASoC: Intel: bytcr_rt5640: Add quirk for ARCHOS Cesium 140
+
+From: Chris Chiu <chiu@endlessos.org>
+
+[ Upstream commit 1bea2256aa96a2d7b1b576eb74e29d79edc9bea8 ]
+
+Tha ARCHOS Cesium 140 tablet has problem with the jack-sensing,
+thus the heaset functions are not working.
+
+Add quirk for this model to select the correct input map, jack-detect
+options and channel map to enable jack sensing and headset microphone.
+This device uses IN1 for its internal MIC and JD2 for jack-detect.

+Subject: drm/msm/a5xx: Remove overwriting A5XX_PC_DBG_ECO_CNTL register
+
+From: AngeloGioacchino Del Regno <angelogioacchino.delregno@somainline.org>
+
+[ Upstream commit 8f03c30cb814213e36032084a01f49a9e604a3e3 ]
+
+The PC_DBG_ECO_CNTL register on the Adreno A5xx family gets
+programmed to some different values on a per-model basis.
+At least, this is what we intend to do here;
+
+Unfortunately, though, this register is being overwritten with a
+static magic number, right after applying the GPU-specific
+configuration (including the GPU-specific quirks) and that is
+effectively nullifying the efforts.
+
+Let's remove the redundant and wrong write to the PC_DBG_ECO_CNTL
+register in order to retain the wanted configuration for the
+target GPU.

+Subject: HID: mf: add support for 0079:1846 Mayflash/Dragonrise USB Gamecube
+ Adapter
+
+From: Ethan Warth <redyoshi49q@gmail.com>
+
+[ Upstream commit 1008230f2abeb624f6d71b2e1c424fa4eeebbf84 ]
+
+Mayflash/Dragonrise seems to have yet another device ID for one of their
+Gamecube controller adapters. Previous to this commit, the adapter
+registered only one /dev/input/js* device, and all controller inputs (from
+any controller) were mapped to this device. This patch defines the 1846
+USB device ID and enables the HID_QUIRK_MULTI_INPUT quirk for it, which
+fixes that (with the patch, four /dev/input/js* devices are created, one
+for each of the four controller ports).

+Subject: media: cx23885: add more quirks for reset DMA on some AMD IOMMU
+
+From: Daniel Lee Kruse <daniel.lee.kruse@protonmail.com>
+
+[ Upstream commit dbf0b3a7b719eb3f72cb53c2ce7d34a012a9c261 ]
+
+On AMD Family 15h (Models 30h-3fh), I/O Memory Management Unit
+RiSC engine sometimes stalls, requiring a reset.
+
+As result, MythTV and w-scan won't scan channels on the AMD Kaveri
+APU with the Hauppauge QuadHD TV tuner card.
+
+For the solution I added the Input/Output Memory Management Unit's PCI
+Identity of 0x1423 to the broken_dev_id[] array, which is used by
+a quirks logic meant to fix similar problems with other AMD
+chipsets.

+Subject: misc: eeprom_93xx46: Add quirk to support Microchip 93LC46B eeprom
+
+From: Aswath Govindraju <a-govindraju@ti.com>
+
+[ Upstream commit f6f1f8e6e3eea25f539105d48166e91f0ab46dd1 ]
+
+A dummy zero bit is sent preceding the data during a read transfer by the
+Microchip 93LC46B eeprom (section 2.7 of[1]). This results in right shift
+of data during a read. In order to ignore this bit a quirk can be added to
+send an extra zero bit after the read address.
+
+Add a quirk to ignore the zero bit sent before data by adding a zero bit
+after the read address.

+
+This is a deadlock caused by calling cancel_work_sync() in
+mwifiex_cleanup_pcie():
+
+- Device resets are done via mwifiex_pcie_card_reset()
+- which schedules card->work to call mwifiex_pcie_card_reset_work()
+- which calls pci_try_reset_function().
+- This leads to mwifiex_pcie_reset_done() be called on the same workqueue,
+ which in turn calls
+- mwifiex_reinit_sw() and that calls
+- _mwifiex_fw_dpc().
+
+The problem is now that _mwifiex_fw_dpc() calls mwifiex_free_adapter()
+in case firmware initialization fails. That ends up calling
+mwifiex_cleanup_pcie().
+
+Note that all those calls are still running on the workqueue. So when
+mwifiex_cleanup_pcie() now calls cancel_work_sync(), it's really waiting
+on itself to complete, causing a deadlock.
+
+This commit fixes the deadlock by skipping cancel_work_sync() on a reset
+failure path.
+
+After this commit, when reset fails, the following output is
+expected to be shown:
+
+ kernel: mwifiex_pcie 0000:03:00.0: info: _mwifiex_fw_dpc: unregister device
+ kernel: mwifiex: Failed to bring up adapter: -5
+ kernel: mwifiex_pcie 0000:03:00.0: reinit failed: -5
+
+To reproduce this issue, for example, try putting the root port of wifi
+into D3 (replace "00:1d.3" with your setup).
+
+ # put into D3 (root port)
+ sudo setpci -v -s 00:1d.3 CAP_PM+4.b=0b

+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit 82cb8a5c395ea5be20e0fe31a8fe84380a502ca5 ]
+
+Not all devices supporting WMID_GUID3 support the wmid3_set_function_mode()
+call, leading to errors like these:
+
+[ 60.138358] acer_wmi: Enabling RF Button failed: 0x1 - 0xff
+[ 60.140036] acer_wmi: Enabling Launch Manager failed: 0x1 - 0xff
+
+Add an ACER_CAP_SET_FUNCTION_MODE capability flag, so that these calls
+can be disabled through the new force_caps mechanism.

+Subject: platform/x86: acer-wmi: Add new force_caps module parameter
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit 39aa009bb66f9d5fbd1e58ca4aa03d6e6f2c9915 ]
+
+Add a new force_caps module parameter to allow overriding the drivers
+builtin capability detection mechanism.
+
+This can be used to for example:
+-Disable rfkill functionality on devices where there is an AA OEM DMI
+ record advertising non functional rfkill switches
+-Force loading of the driver on devices with a missing AA OEM DMI record
+
+Note that force_caps is -1 when unset, this allows forcing the
+capability field to 0, which results in acer-wmi only providing WMI
+hotkey handling while disabling all other (led, rfkill, backlight)
+functionality.

+Subject: platform/x86: acer-wmi: Add support for SW_TABLET_MODE on Switch
+ devices
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit 5c54cb6c627e8f50f490e6b5656051a5ac29eab4 ]
+
+Add support for SW_TABLET_MODE on the Acer Switch 10 (SW5-012) and the
+acer Switch 10 (S1003) models.
+
+There is no way to detect if this is supported, so this uses DMI based
+quirks setting force_caps to ACER_CAP_KBD_DOCK (these devices have no
+other acer-wmi based functionality).
+
+The new SW_TABLET_MODE functionality can be tested on devices which
+are not in the DMI table by passing acer_wmi.force_caps=0x40 on the
+kernel commandline.

+Subject: platform/x86: acer-wmi: Cleanup accelerometer device handling
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit 9feb0763e4985ccfae632de3bb2f029cc8389842 ]
+
+Cleanup accelerometer device handling:
+-Drop acer_wmi_accel_destroy instead directly call input_unregister_device.
+-The information tracked by the CAP_ACCEL flag mirrors acer_wmi_accel_dev
+ being NULL. Drop the CAP flag, this is a preparation change for allowing
+ users to override the capability flags. Dropping the flag stops users
+ from causing a NULL pointer dereference by forcing the capability.
