Kai-Heng Feng 7ecacafc24 Bluetooth: btusb: Disable runtime suspend on Realtek devices After commit `9e45524a01` ("Bluetooth: btusb: Fix suspend issue for Realtek devices") both WiFi and Bluetooth stop working after reboot: [ 34.322617] usb 1-8: reset full-speed USB device number 3 using xhci_hcd [ 34.450401] usb 1-8: device descriptor read/64, error -71 [ 34.694375] usb 1-8: device descriptor read/64, error -71 ... [ 44.599111] rtw_pci 0000:02:00.0: failed to poll offset=0x5 mask=0x3 value=0x0 [ 44.599113] rtw_pci 0000:02:00.0: mac power on failed [ 44.599114] rtw_pci 0000:02:00.0: failed to power on mac [ 44.599114] rtw_pci 0000:02:00.0: leave idle state failed [ 44.599492] rtw_pci 0000:02:00.0: failed to leave ips state [ 44.599493] rtw_pci 0000:02:00.0: failed to leave idle state That commit removed USB_QUIRK_RESET_RESUME, which not only resets the USB device after resume, it also prevents the device from being runtime suspended by USB core. My experiment shows if the Realtek btusb device ever runtime suspends once, the entire wireless module becomes useless after reboot. So let's explicitly disable runtime suspend on Realtek btusb device for now.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
