2022-08-25spi: amd: Configure device speedLucas Tanure1-0/+97
Number of clock frequencies are supported by AMD controller which are mentioned in the amd_spi_freq structure table. Create mechanism to configure device clock frequency such that it is strictly less than the requested frequency. Give priority to the device transfer speed and in case it is not set then use the max clock speed supported by the device.

2022-08-25xen/privcmd: fix error exit of privcmd_ioctl_dm_op()Juergen Gross1-10/+11
The error exit of privcmd_ioctl_dm_op() is calling unlock_pages() potentially with pages being NULL, leading to a NULL dereference. Additionally lock_pages() doesn't check for pin_user_pages_fast() having been completely successful, resulting in potentially not locking all pages into memory. This could result in sporadic failures when using the related memory in user mode. Fix all of that by calling unlock_pages() always with the real number of pinned pages, which will be zero in case pages being NULL, and by checking the number of pages pinned by pin_user_pages_fast() matching the expected number of pages.

2022-08-25platform/x86: asus-wmi: Simplify tablet-mode-switch handlingHans de Goede2-73/+16
Simplify tablet-mode-switch handling: 1. The code is the same for all variants, the only difference is the dev_id and notify event code. Store the dev_id + code in struct asus_wmi and unify the handling 2. Make the new unified asus_wmi_tablet_mode_get_state() check dev_id has been set and make it a no-op when not set. This allows calling it unconditionally at resume/restore time 3. Simplify the tablet_mode_sw module-param handling, this also allows selecting the new lid-flip-rog type through the module-param.

However this one is intended to control only audio pins in particular, which can not be configured/touched by the Top level SoC pin controller except setting them as gpios. Apart from this, slew rate is also available in this block for certain pins which are connected to SLIMbus or SoundWire Bus.

2022-08-25pinctrl: rockchip: Enhance support for IRQ_TYPE_EDGE_BOTHJoão H. Spies1-2/+2
Switching between falling/rising edges for IRQ_TYPE_EDGE_BOTH on pins that require debounce can cause the device to lose events due to a desync between pin state and irq type. This problem is resolved by switching between IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_LEVEL_HIGH instead. Fixes: 936ee2675eee ("gpio/rockchip: add driver for rockchip gpio") Signed-off-by: João H.

Make acpi_cpc_valid() check if ACPI is disabled, so that its callers don't need to check that separately. This will also cause the AMD pstate driver to refuse to load right away when ACPI is disabled. Also update the warning message in amd_pstate_init() to mention the ACPI disabled case for completeness.

2022-08-25regulator: pfuze100: Fix the global-out-of-bounds access in pfuze100_regulator_probe()Xiaolei Wang1-1/+1
The pfuze_chip::regulator_descs is an array of size PFUZE100_MAX_REGULATOR, the pfuze_chip::pfuze_regulators is the pointer to the real regulators of a specific device. The number of real regulator is supposed to be less than the PFUZE100_MAX_REGULATOR, so we should use the size of 'regulator_num * sizeof(struct pfuze_regulator)' in memcpy(). This fixes the out of bounds access bug reported by KASAN.

2022-08-25ACPI: property: Ignore already existing data node tagsSakari Ailus1-1/+1
ACPI node pointers are attached to data node handles, in order to resolve string references to them. _DSD guide allows the same node to be reached from multiple parent nodes, leading the node enumeration algorithm to each such nodes more than once. As attached data already already exists, attaching data with the same tag will fail. Address this problem by ignoring nodes that have been already tagged.

2022-08-25dma-buf/dma-resv: check if the new fence is really laterChristian König1-1/+2
Previously when we added a fence to a dma_resv object we always assumed the the newer than all the existing fences. With Jason's work to add an UAPI to explicit export/import that's not necessary the case any more. So without this check we would allow userspace to force the kernel into an use after free error. Since the change is very small and defensive it's probably a good idea to backport this to stable kernels as well just in case others are using the dma_resv object in the same way.
