2022-12-08wifi: rtl8xxxu: Add __packed to struct rtl8723bu_c2hBitterblue Smith
This struct is used to access a sequence of bytes received from the wifi chip. It must not have any padding bytes between the members. This doesn't change anything on my system, possibly because currently none of the members need more than byte alignment.

2022-12-08wifi: brcmfmac: add support for vendor-specific firmware apiArend van Spriel
The driver is being used by multiple vendors who develop the firmware api independently. So far the firmware api as used by the driver has not diverged (yet). This change adds framework for supporting multiple firmware apis. The vendor-specific support code has to provide a number of callback operations. Right now it is only attach and detach callbacks so no real functionality as the api is still common. This code only adds WCC variant anyway, which is selected for all devices right now. The vendor-specific part will be built in a separate module when the driver is configured to be built as a module through Kconfig, ie. when CONFIG_BRCMFMAC=m.

2022-12-08mfd: Drop obsolete dependencies on COMPILE_TESTJean Delvare
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. As a minor optimization, this also lets us drop of_match_ptr(), as we now know what it will resolve to, we might as well save cpp some work.

2022-12-08regulator: core: Use different devices for resource allocation and DT lookupChiYuan Huang
Following by the below discussion, there's the potential UAF issue between regulator and mfd. https://lore.kernel.org/all/20221128143601.1698148-1-yangyingliang@huawei.com/ From the analysis of Yingliang CPU A |CPU B mt6370_probe() | devm_mfd_add_devices() | |mt6370_regulator_probe() | regulator_register() | //allocate init_data and add it to devres | regulator_of_get_init_data() i2c_unregister_device() | device_del() | devres_release_all() | // init_data is freed | release_nodes() | | // using init_data causes UAF | regulator_register() It's common to use mfd core to create child device for the regulator. In order to do the DT lookup for init data, the child that registered the regulator would pass its parent as the parameter. And this causes init data resource allocated to its parent, not itself. The issue happen when parent device is going to release and regulator core is still doing some operation of init data constraint for the regulator of child device. To fix it, this patch expand 'regulator_register' API to use the different devices for init data allocation and DT lookup.

2022-12-08spi: spi-gpio: Don't set MOSI as an input if not 3WIRE modeKris Bahnsen
The addition of 3WIRE support would affect MOSI direction even when still in standard (4 wire) mode. This can lead to MOSI being at an invalid logic level when a device driver sets an SPI message with a NULL tx_buf. spi.h states that if tx_buf is NULL then "zeros will be shifted out ... " If MOSI is tristated then the data shifted out is subject to pull resistors, keepers, or in the absence of those, noise. This issue came to light when using spi-gpio connected to an ADS7843 touchscreen controller. MOSI pulled high when clocking MISO data in caused the SPI device to interpret this as a command which would put the device in an unexpected and non-functional state.

2022-12-07net: ethernet: ti: am65-cpsw: Add suspend/resume supportRoger Quadros
Add PM handlers for System suspend/resume. As DMA driver doesn't yet support suspend/resume we free up the DMA channels at suspend and acquire and initialize them at resume. In this revised approach we do not free the TX/RX IRQs at am65_cpsw_nuss_common_stop() as it causes problems. We will now free them only on .suspend() as we need to release the DMA channels (as DMA looses context) and re-acquiring them on .resume() may not necessarily give us the same IRQs. To make this easier: - introduce am65_cpsw_nuss_remove_rx_chns() which is similar to am65_cpsw_nuss_remove_tx_chns(). These will be invoked in pm.suspend() to release the DMA channels and free up the IRQs. - move napi_add() and request_irq() calls to am65_cpsw_nuss_init_rx/tx_chns() so we can invoke them in pm.resume() to acquire the DMA channels and IRQs. As CPTS looses contect during suspend/resume, invoke the necessary CPTS suspend/resume helpers. ALE_CLEAR command is issued in cpsw_ale_start() so no need to issue it before the call to cpsw_ale_start().

It is not allowed to call kfree_skb() or consume_skb() from hardware interrupt context or with interrupts being disabled. So replace kfree_skb/dev_kfree_skb() with dev_kfree_skb_irq() and dev_consume_skb_irq() under spin_lock_irq().
