Subject: HID: wacom: close the wireless receiver on remove()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f6205161782fa325152340c8fe47c1b90105cfbc;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

HID: wacom: close the wireless receiver on remove()

rmmod/insmod the wacom.ko module does not work for the receiver because
it was not previously closed. Now, we can hack with the wireless receiver
without having to unplug/replug it.
