This driver often takes on the order of 10ms to start, but in some cases takes more than 100ms. It shouldn't have many cross-device dependencies to race with, nor racy access to shared state with other drivers, so this should be a relatively low risk change. This driver was pinpointed as part of a survey of top slowest initcalls (i.e., are built in, and probing synchronously) on a lab of ChromeOS systems. Signed-off-by:

Convert the usb251xb hub DT bindings from text to yaml schema so it is possible to validate DTs against the schema. Adjust the example to describe two different hubs at different I2C bus addresses, to avoid I2C address collission in the example. Reviewed-by:

Ray Chi authored
When a broken USB accessory connects to a USB host, usbcore might keep doing enumeration retries. If the host has a watchdog mechanism, the kernel panic will happen on the host. This patch provides an attribute early_stop to limit the numbers of retries for each port of a hub. If a port was marked with early_stop attribute, unsuccessful connection attempts will fail quickly. In addition, if an early_stop port has failed to initialize, it will ignore all future connection events until early_stop attribute is clear. Signed-off-by:

Thinh Nguyen authored
When the TRB ring is full, the dwc3 driver must make sure that there's at least 1 TRB with Interrupt On Completion (IOC) set to notify of available TRBs. The current logic just sets the TRB's IOC whenever we run out of TRBs, but it doesn't consider that there may be other TRBs with IOC/LST set already. This creates more events and unnecessary delay from interrupt handling. Only forcefully set IOC when we run out of TRBs and none of the TRBs in the TRB ring has had IOC set. Signed-off-by:

Make it possible to probe the GPIO VBUS detection driver from the device tree compatible for GPIO USB B connectors. Since this driver is using the "gpio-usb-b-connector" compatible, it is important to discern it from the role switch connector driver (which does not provide a phy), so we add some Kconfig text and depend on !USB_CONN_GPIO.

Alan Stern authored
It has been pointed out that the kernel log messages warning about problems in USB configuration and related descriptors are vexing for users. The warning log level has a fairly high priority, but the user can do nothing to fix the underlying errors in the device's firmware. To reduce the amount of useless information produced by tools that filter high-priority log messages, we can change these warnings to notices, i.e., change dev_warn() to dev_notice(). The same holds for a few messages that currently use dev_err(): Unless they indicate a failure that might make a device unusable (such as inability to transfer a config descriptor), change them to dev_notice() also.

Currently the return value of 'sub_driver->init' is not checked. If sparse_keymap_setup() called in the init function fails, 'generic_ inputdev' is freed, then it will lead a UAF when using it in generic_ acpi_laptop_init(). Fix it by checking the return value and setting generic_inputdev to NULL after free, so as to avoid double free it. The error code in generic_subdriver_init() is always negative, so the return of generic_subdriver_init() can be simplified.

Pull ACPI and device properties fixes from Rafael Wysocki: "These fix device properties documentation and the ACPI PCC code, add a new IRQ override quirk for resource handling and add one more item to the list of device IDs to be ignored when returned by _DEP. Specifics: - Fix the documentation of the *_match_string() family of functions to properly cover the return value (Andy Shevchenko) - Fix a possible integer overflow during multiplication in the ACPI PCC code (Manank Patel) - Make the ACPI device resources code skip IRQ override on Asus Vivobook S5602ZA (Tamim Khan) - Add LATT2021 to the list of device IDs that are ignored when returned by _DEP, because there are no drivers for them in the kernel and no plans to add such drivers (Hans de Goede)" * tag 'acpi-6.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: scan: Add LATT2021 to acpi_ignore_dep_ids[] ACPI: resource: Skip IRQ override on Asus Vivobook S5602ZA ACPI: PCC: Fix unintentional integer overflow device property: Fix documentation for *_match_string() APIs

Pull power management fixes from Rafael Wysocki: "These make the intel_pstate driver work as expected on all hybrid platforms to date (regardless of possible platform firmware issues), fix hybrid sleep on systems using suspend-to-idle by default, make the generic power domains code handle disabled idle states properly and update pm-graph. Specifics: - Make intel_pstate use what is known about the hardware instead of relying on information from the platform firmware (ACPI CPPC in particular) to establish the relationship between the HWP CPU performance levels and frequencies on all hybrid platforms available to date (Rafael Wysocki) - Allow hybrid sleep to use suspend-to-idle as a system suspend method if it is the current suspend method of choice (Mario Limonciello) - Fix handling of unavailable/disabled idle states in the generic power domains code (Sudeep Holla) - Update the pm-graph suite of utilities to version 5.10 which is fixes-mostly and does not add any new features (Todd Brandt)" * tag 'pm-6.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM: domains: Fix handling of unavailable/disabled idle states pm-graph v5.10 cpufreq: intel_pstate: hybrid: Use known scaling factor for P-cores cpufreq: intel_pstate: Read all MSRs on the target CPU PM: hibernate: Allow hybrid sleep to work with s2idle

While reworking the archrandom handling, commit d349ab99 ("random: handle archrandom with multiple longs") switched to the non-early archrandom helpers in random_init(), which broke initialization of the entropy pool from the arm64 random generator. Indeed at that point the arm64 CPU features, which verify that all CPUs have compatible capabilities, are not finalized so arch_get_random_seed_longs() is unsuccessful. Instead random_init() should use the _early functions, which check only the boot CPU on arm64. On other architectures the _early functions directly call the normal ones.

lru_gen_add_mm() has been added within an IRQ-off region in the commit mentioned below. The other invocations of lru_gen_add_mm() are not within an IRQ-off region. The invocation within IRQ-off region is problematic on PREEMPT_RT because the function is using a spin_lock_t which must not be used within IRQ-disabled regions. The other invocations of lru_gen_add_mm() occur while task_struct::alloc_lock is acquired. Move lru_gen_add_mm() after interrupts are enabled and before task_unlock().

Before the do-while loop in mtree_range_walk(), the variables next, min, max need to be initialized. The variables last, prev_min and prev_max are set within the loop body before they are eventually used after exiting the loop body. As it is a do-while loop, the loop body is executed at least once, so the variables last, prev_min and prev_max do not need to be initialized before the loop body. Remove unneeded initialization of last and prev_min. The needless initialization was reported by clang-analyzer as Dead Stores. As the compiler already identifies these assignments as unneeded, it optimizes the assignments away. Hence: No functional change. No change in object code.
