[PATCH v1 2/3] HID: intel-ish-hid: Simplify logic in ishtp_cl_device_remove()

From: Uwe Kleine-König
Date: Sat Feb 06 2021 - 10:14:53 EST


There is only a single change in behavior: Now dev->driver isn't modified.
Assigning to this variable is in the domain of the driver core only. (And
it's done in __device_release_driver shortly after bus->remove() (i.e
ishtp_cl_device_remove() here) returns.)
