Subject: Staging: comedi: usbdux: don't initialize semaphores on init
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ab3795270d3a7985be40ae325d3366cf018fc9dd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

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

This patch removes usbdux 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.
