  "message": "USB: ch341 serial: fix port number changed after resume\n\nThis patch fixes the following bug:\n\t.plug ch341 usb serial port into a hub port;\n\t.ch341 driver bound to the device and /dev/ttyUSB0 comes\n\t.open /dev/ttyUSB0 by minicom and we can use the serial successfully\n\t.suspend the ch341 usb serial device(such as: echo suspend \u003e power/level)\n\t.resume the ch341 usb serial device (such as: echo on \u003e power/level)\n\t.new port /dev/ttyUSB1 comes ,and the original /dev/ttyUSB0 still exists,\nbut is no longer usable by minicom\n\nThe patch adds suspend and resume callback to ch341 usb driver to prevent it\nfrom unbinding during suspend. The /dev/ttyUSB0 is not released until being\nclosed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is\nno longer usable by minicom. It is really a mess for a minicom user.\n\nThis patch also adds the reset_resume callback to make it usable after resuming\nfrom STR or hibernation, for generally STR or hibernation will make the vbus\nof root-hub lost.\n\nFinally enable the driver\u0027s supports_autosuspend, for the device is in working\norder with it.\n\nSigned-off-by: Ming Lei \u003ctom.leiming@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
