* platform/x86: intel: int0002_vgpio: Make the irqchip immutableHans de Goede2024-12-101-2/+12
| | | | | | | | | | | | | | | | Commit 6c846d026d49 ("gpio: Don't fiddle with irqchips marked as immutable") added a warning to indicate if the gpiolib is altering the internals of irqchips: gpio gpiochip4: (INT0002 Virtual GPIO): not an immutable chip, please consider fixing it! Fix this by making the irqchip in the int0002_vgpio driver immutable.

* platform/x86: Switch back to struct platform_driver::remove()Uwe Kleine-König2024-10-171-2/+2
| | | | | | | | | | | | | | | | | | | | After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/platform/x86/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

* platform/x86: intel: int0002_vgpio: Pass IRQF_ONESHOT to request_irq()Hans de Goede2024-02-191-1/+1
| | | | | | | | | | | | | | | | | Since commit 7a36b901a6eb ("ACPI: OSL: Use a threaded interrupt handler for SCI") the ACPI OSL code passes IRQF_ONESHOT when requesting the SCI. Since the INT0002 GPIO is typically shared with the ACPI SCI the INT0002 driver must pass the same flags. This fixes the INT0002 driver failing to probe due to following error + as well as removing the backtrace that follows this error: "genirq: Flags mismatch irq 9. 00000084 (INT0002) vs. 00002080 (acpi)" Fixes: 7a36b901a6eb ("ACPI: OSL: Use a threaded interrupt handler for SCI") Signed-off-by: Hans de Goede <[email protected]> Link: https://lore.kernel.org/r/[email protected]
* platform/x86: intel: int0002_vgpio: Convert to platform remove callback ↵Uwe Kleine-König2023-03-071-3/+2
| | | | | | | | | | | | | | | | | | | | returning void 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 (mostly) ignored 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. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

* platform/x86: intel_int0002_vgpio: Use generic_handle_irq_safe()Sebastian Andrzej Siewior2022-09-191-2/+1
| | | | | | | | | | | | | | | | On PREEMPT_RT enabled kernels the demultiplex interrupt handler is force threaded and runs with interrupts enabled. The invocation of generic_handle_irq() with interrupts enabled triggers a lockdep warning due to a non-irq safe lock acquisition. Instead of disabling interrupts on the driver level, use generic_handle_domain_irq_safe().
