Subject: Staging: comedi: usbduxfast: don't initialize semaphores on init
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3944969427e11f3081d676c16cebeff4060ce992;p=linux-beck.git

Staging: comedi: usbduxfast: don't initialize semaphores on init

This patch removes usbduxfast semaphores initialization
from init function as they are initialized later on in
probe function. Also remove init_usb_devices() as it is
not needed anymore.
