[PATCH 15/15] staging: comedi: usbduxsigma: use comedi_load_firmware()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use comedi_load_firmware() instead of duplicating the code in a
private function.

Also, rename firmwareUpload() to have namespace associated with
the driver.
