The declaration is in an #ifdef, which causes warnings when building with 'make W=1' and without CONFIG_PM: drivers/usb/core/devio.c:742:6: error: no previous prototype for 'usbfs_notify_suspend' drivers/usb/core/devio.c:747:6: error: no previous prototype for 'usbfs_notify_resume' Use the same #ifdef check around the function definitions to avoid the warnings and slightly shrink the USB core.

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. We thus need to guard sections of code calling them as alternative access methods with CONFIG_HAS_IOPORT checks. For uhci-hcd there are a lot of I/O port uses that do have MMIO alternatives all selected by uhci_has_pci_registers() so this can be handled by UHCI_IN/OUT macros and making uhci_has_pci_registers() constant 0 if CONFIG_HAS_IOPORT is unset.

ISOC transfers expect a certain cadence of requests being queued. Not keeping up with the expected rate of requests results in missed ISOC transfers (EXDEV). The application layer may or may not produce video frames to match this expectation, so uvc gadget driver must handle cases where the application is not queuing up buffers fast enough to fulfill ISOC requirements. Currently, uvc gadget driver waits for new video buffer to become available before queuing up usb requests. With this patch the gadget driver queues up 0 length usb requests whenever there are no video buffers available. The USB controller's complete callback is used as the limiter for how quickly the 0 length packets will be queued. Video buffers are still queued as soon as they become available.

When serial console over USB is enabled, gs_console_connect queues gs_console_work, where it acquires the spinlock and queues the usb request, and this request goes to gadget layer. Now consider a situation where gadget layer prints something to dmesg, this will eventually call gs_console_write() which requires cons->lock. And this causes spinlock recursion. Avoid this by excluding usb_ep_queue from the spinlock. spin_lock_irqsave //needs cons->lock gs_console_write . . _printk __warn_printk dev_warn/pr_err . . [USB Gadget Layer] . . usb_ep_queue gs_console_work __gs_console_push // acquires cons->lock process_one_work Signed-off-by:

Consider a case where gserial_disconnect has already cleared gser->ioport. And if gserial_suspend gets called afterwards, it will lead to accessing of gser->ioport and thus causing null pointer dereference. Avoid this by adding a null pointer check. Added a static spinlock to prevent gser->ioport from becoming null after the newly added null pointer check. Fixes: aba3a8d0 ("usb: gadget: u_serial: add suspend resume callbacks") Signed-off-by:

The VBUS driver needs to know the regulator-min-microamp and regulator-max-microamp so they should both be marked as required. regulator.yaml defines those two dependencies so include regulator.yaml. We need to change from additionalProperties: false to unevaluatedProperties: false. Reviewed-by:

The regulator code needs to know the location of the register to write to to switch on/off. Right now we have a driver that does this, a yaml that partially describes it and no dts that uses it. Switching on the VBUS for sm8250 shows that we haven't documented reg as a required property, do so now. Acked-by:

power_supply_is_system_supplied() checks whether any power supplies are present that aren't batteries to decide whether the system is running on DC or AC. Downstream drivers use this to make performance decisions. Navi dGPUs include an UCSI function that has been exported since commit 17631e8c ("i2c: designware: Add driver support for AMD NAVI GPU"). This UCSI function registers a power supply since commit 992a60ed ("usb: typec: ucsi: register with power_supply class") but this is not a system power supply. As the power supply for a dGPU is only for powering devices connected to dGPU, create a device property to indicate that the UCSI endpoint is only for the scope of `POWER_SUPPLY_SCOPE_DEVICE`.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
