Because of the too generic DMI strings this entry is also doing bios-date matching, so the gpd_micropc data struct may very well need to be updated with some extra bios-dates in the future. Acked-by:

[ Upstream commit 3b00691c ] 24 bit expanders use REG_ADDR_AI in combination with register addressing. This conflicts with regmap which takes this bit as part of the register number, i.e. a second cache entry is defined for accessed with REG_ADDR_AI being set although on the chip it is the same register as with REG_ADDR_AI being cleared. The problem was introduced by commit b32cecb4 ("gpio: pca953x: Extract the register address mangling to single function") but only became visible by commit 8b9f9d4d ("regmap: verify if register is writeable before writing operations") because before, the regmap size was effectively ignored and pca953x_writeable_register() did know to ignore REG_ADDR_AI. Still, there were two separate cache entries created. Since the use of REG_ADDR_AI seems to be static we can work around this issue by simply increasing the size of the regmap to cover the "virtual" registers with REG_ADDR_AI being set. This only means that half of the regmap buffer will be unused. Reported-by:

[ Upstream commit 04268bf2 ] When we call snd_soc_component_set_jack(component, NULL, NULL) we should set rt274->jack to passed jack, so when interrupt is triggered it calls snd_soc_jack_report(rt274->jack, ...) with proper value. This fixes problem in machine where in register, we call snd_soc_register(component, &headset, NULL), which just calls rt274_mic_detect via callback. Now when machine driver is removed "headset" will be gone, so we need to tell codec driver that it's gone with: snd_soc_register(component, NULL, NULL), but we also need to be able to handle NULL jack argument here gracefully. If we don't set it to NULL, next time the rt274_irq runs it will call snd_soc_jack_report with first argument being invalid pointer and there will be Oops. Signed-off-by:

[ Upstream commit 6d647b73 ] During the integration of HDaudio support, we changed the way in which we get hdev in snd_hdac_ext_bus_device_init() to use one preallocated with devm_kzalloc(), however it still left kfree(hdev) in snd_hdac_ext_bus_device_exit(). It leads to oopses when trying to rmmod and modprobe. Fix it, by just removing kfree call. SOF also uses some of the snd_hdac_ functions for HDAudio support but allocated the memory with kzalloc. A matching fix is provided separately to align all users of the snd_hdac_ library. Fixes: 6298542f ("ALSA: hdac: remove memory allocation from snd_hdac_ext_bus_device_init") Reviewed-by:

[ Upstream commit 70fc5373 ] Kernel crashes when an ASoC component rebinding. The dai_link->platforms has been reset to NULL by soc_cleanup_platform() in soc_cleanup_card_resources() when un-registering component. However, it has no chance to re-allocate the dai_link->platforms when registering the component again. Move the DAI pre-links initiation from snd_soc_register_card() to snd_soc_instantiate_card() to make sure all DAI pre-links get initiated when component rebinding. As an example, by using the following commands: - echo -n max98357a > /sys/bus/platform/drivers/max98357a/unbind - echo -n max98357a > /sys/bus/platform/drivers/max98357a/bind Got the error message: "Unable to handle kernel NULL pointer dereference at virtual address".

[ Upstream commit 066cfd07 ] The patch 10209abe usb: dwc2: gadget: Add scatter-gather mode avoided a NULL pointer dereference (hs_ep->req == NULL) by calling dwc2_gadget_fill_nonisoc_xfer_dma_one() directly instead of through the dwc2_gadget_config_nonisoc_xfer_ddma() wrapper, which unconditionally dereferenced the said pointer. However, this was based on an incorrect assumption that in the context of dwc2_hsotg_program_zlp() the pointer is always NULL, which is not the case. The result were SB CV MSC tests failing starting from Test Case 6. Instead, this patch reverts to calling the wrapper and adds a check for the pointer being NULL inside the wrapper.

[ Upstream commit 2458d9d6 ] mtk_dsi_stop() should be called after mtk_drm_crtc_atomic_disable(), which needs ovl irq for drm_crtc_wait_one_vblank(), since after mtk_dsi_stop() is called, ovl irq will be disabled. If drm_crtc_wait_one_vblank() is called after last irq, it will timeout with this message: "vblank wait timed out on crtc 0". This happens sometimes when turning off the screen. In drm_atomic_helper.c#disable_outputs(), the calling sequence when turning off the screen is: 1. mtk_dsi_encoder_disable() --> mtk_output_dsi_disable() --> mtk_dsi_stop(); /* sometimes make vblank timeout in atomic_disable */ --> mtk_dsi_poweroff(); 2. mtk_drm_crtc_atomic_disable() --> drm_crtc_wait_one_vblank(); ... --> mtk_dsi_ddp_stop() --> mtk_dsi_poweroff(); mtk_dsi_poweroff() has reference count design, change to make mtk_dsi_stop() called in mtk_dsi_poweroff() when refcount is 0.

[ Upstream commit f0fd8483 ] Unbinding components (i.e. mtk_dsi and mtk_disp_ovl/rdma/color) will trigger master(mtk_drm)'s .unbind(), and currently mtk_drm's unbind won't actually unbind components. During the next bind, mtk_drm_kms_init() is called, and the components are added back. .unbind() should call mtk_drm_kms_deinit() to unbind components. And since component_master_del() in .remove() will trigger .unbind(), which will also unregister device, it's fine to remove original functions called here.

[ Upstream commit d6947bb2 ] HDA_DEV_ASOC type codec device refcounts are managed differently from HDA_DEV_LEGACY devices. The refcount is released explicitly in snd_hdac_ext_bus_device_remove() for ASOC type devices. So, remove the put_device() call in snd_hda_codec_dev_free() for such devices to make the refcount balanced. This will prevent the NULL pointer exception when the codec driver is released after the card is freed. Signed-off-by:

[ Upstream commit 3e951e79 ] This tablet has an incorrect acpi identifier just like Thinkpad10 tablet, which is why it is trying to load the RT5640 driver instead of the RT5762 driver. The RT5640 driver, on the other hand, checks the hardware ID, so no driver are loaded during boot. This fix resolves to load the RT5672 driver on this tablet during boot. It also provides the correct IO configuration, like the jack detect mode 3, for 1.8V pullup. I would like to thank Pierre-Louis Bossart for helping with this patch. Signed-off-by:

commit 5c089fd0 upstream. If the entry is deleted from the IDR between the call to radix_tree_iter_find() and rcu_dereference_raw(), idr_get_next() will return NULL, which will end the iteration prematurely. We should instead continue to the next entry in the IDR. This only happens if the iteration is protected by the RCU lock. Most IDR users use a spinlock or semaphore to exclude simultaneous modifications. It was noticed once the PID allocator was converted to use the IDR, as it uses the RCU lock, but there may be other users elsewhere in the kernel. We can't use the normal pattern of calling radix_tree_deref_retry() (which catches both a retry entry in a leaf node and a node entry in the root) as the IDR supports storing entries which are unaligned, which will trigger an infinite loop if they are encountered. Instead, we have to explicitly check whether the entry is a retry entry. Fixes: 0a835c4f ("Reimplement IDR and IDA using the radix tree") Reported-by:
