2022-01-05can: mcp251x: mcp251x_gpio_setup(): Get rid of duplicate of_node assignmentAndy Shevchenko
GPIO library does copy the of_node from the parent device of the GPIO chip, there is no need to repeat this in the individual drivers. Remove assignment here. For the details one may look into the of_gpio_dev_init() implementation.

2022-01-05dmaengine: idxd: change MSIX allocation based on per wq activationDave Jiang
Change the driver where WQ interrupt is requested only when wq is being enabled. This new scheme set things up so that request_threaded_irq() is only called when a kernel wq type is being enabled. This also sets up for future interrupt request where different interrupt handler such as wq occupancy interrupt can be setup instead of the wq completion interrupt. Not calling request_irq() until the WQ actually needs an irq also prevents wasting of CPU irq vectors on x86 systems, which is a limited resource. idxd_flush_pending_descs() is moved to device.c since descriptor flushing is now part of wq disable rather than shutdown().

2022-01-05rtc: pxa: fix null pointer dereferenceLaurence de Bruxelles
With the latest stable kernel versions the rtc on the PXA based Zaurus does not work, when booting I see the following kernel messages: pxa-rtc pxa-rtc: failed to find rtc clock source pxa-rtc pxa-rtc: Unable to init SA1100 RTC sub-device pxa-rtc: probe of pxa-rtc failed with error -2 hctosys: unable to open rtc device (rtc0) I think this is because commit f2997775b111 ("rtc: sa1100: fix possible race condition") moved the allocation of the rtc_device struct out of sa1100_rtc_init and into sa1100_rtc_probe. This means that pxa_rtc_probe also needs to do allocation for the rtc_device struct, otherwise sa1100_rtc_init will try to dereference a null pointer. This patch adds that allocation by copying how sa1100_rtc_probe in drivers/rtc/rtc-sa1100.c does it; after the IRQs are set up a managed rtc_device is allocated. I've tested this patch with `qemu-system-arm -machine akita` and with a real Zaurus SL-C1000 applied to 4.19, 5.4, and 5.10.

2022-01-05rtc: ftrtc010: Use platform_get_irq() to get the interruptLad Prabhakar
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq().
