Subject: rtlwifi: Modify some USB de-initialize code.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=851639fdaeacbf8c0ff73f73da7bc67b525f5ce9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

rtlwifi: Modify some USB de-initialize code.

Delete SET_USB_STOP macro and rtl_usb_deinit because
those are called twice in USB de-initialize routine.
Add some de-initialize workqueue function in USB disconnect routine.
