Running io_watchdog_func() while ohci_urb_enqueue() is running can
cause a race condition where ohci->prev_frame_no is corrupted and the
watchdog can mis-detect following error:
ohci-platform 664a0800.usb: frame counter not updating; disabled

Hi All,
I was going through usb serial driver console related source code
(drivers/usb/serial/console.c) in linux kernel and came across
"usb_console_write" function and was wondering if any usb serial
convertor drivers were using this function? If so any pointers on how
it is being used?

Use GPIO descriptors instead of relying on the old method.
Include irq.h header since it is needed and was indirectly
included through of_gpio.h.

With the removal of AVR platforms, code related to platform stuff
is useless.

The Quectel EP06 is a Cat. 6 LTE modem, and the interface mapping is as
follows:
0: Diag
1: NMEA
2: AT
3: Modem
Interface 4 is QMI and interface 5 is ADB, so they are blacklisted.
This patch should also be considered for -stable. The QMI-patch for this
modem is already in the -stable-queue.
