Anyway, major things here are: - new FSI driver subsystem, yet-another-powerpc low-level hardware bus - gnss, finally an in-kernel GPS subsystem to try to tame all of the crazy out-of-tree drivers that have been floating around for years, combined with some really hacky userspace implementations. This is only for GNSS receivers, but you have to start somewhere, and this is great to see. Other than that, there are new slimbus drivers, new coresight drivers, new fpga drivers, and loads of DT bindings for all of these and existing drivers. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (255 commits) android: binder: Rate-limit debug and userspace triggered err msgs fsi: sbefifo: Bump max command length fsi: scom: Fix NULL dereference misc: mic: SCIF Fix scif_get_new_port() error handling misc: cxl: changed asterisk position genwqe: card_base: Use true and false for boolean values misc: eeprom: assignment outside the if statement uio: potential double frees if __uio_register_device() fails eeprom: idt_89hpesx: clean up an error pointer vs NULL inconsistency misc: ti-st: Fix memory leak in the error path of probe() android: binder: Show extra_buffers_size in trace firmware: vpd: Fix section enabled flag on vpd_section_destroy platform: goldfish: Retire pdev_bus goldfish: Use dedicated macros instead of manual bit shifting goldfish: Add missing includes to goldfish.h mux: adgs1408: new driver for Analog Devices ADGS1408/1409 mux dt-bindings: mux: add adi,adgs1408 Drivers: hv: vmbus: Cleanup synic memory free path Drivers: hv: vmbus: Remove use of slow_virt_to_phys() Drivers: hv: vmbus: Reset the channel callback in vmbus_onoffer_rescind() ...

It does not need <linux/mod_devicetable.h>, so drop that header and explicitly add <linux/mod_devicetable.h> to source files that need it. 4146 #include <linux/platform_device.h> After this patch, there are 225 files that use <linux/mod_devicetable.h>, for a reduction of around 3900 times that <linux/mod_devicetable.h> does not have to be read & parsed. 225 #include <linux/mod_devicetable.h> This patch was build-tested on 20 different arch-es. It also makes these drivers SubmitChecklist#1 compliant.

| | * | | PCI: Add PCI_DEVICE_DATA() macro to fully describe device ID entryAndy Shevchenko2018-08-141-6/+0

Introduce PCI_DEVICE_DATA() macro to fully describe device ID entry in shortest possible form. For example, before: { PCI_VDEVICE(INTEL, PCI_DEVICE_ID_INTEL_MRFLD), (kernel_ulong_t) &dwc3_pci_mrfld_properties, }, after: { PCI_DEVICE_DATA(INTEL, MRFLD, &dwc3_pci_mrfld_properties) }, Drivers can be converted later on in independent way. While here, remove the unused macro with the same name from Ralink wireless driver.

This results in transmission (probe requests) on channels which are not "available" for transmissions. Since the firmware is closed source and nothing can be done from our side to fix the problem in it, the driver has to work around this problem. The WMI_CHAN_FLAG_PASSIVE seems to be interpreted by the firmware to not scan actively on a channel unless an AP was detected on it. Simple probe requests will then be transmitted by the STA on the channel. ath10k must therefore also use this flag when it queues a radar channel for scanning. This should reduce the chance of an active scan when the channel might be "unusable" for transmissions.
