+Subject: [PATCH] Build fixes for Linux 4.15
+
+Fixes two build issues for 4.15:
+
+ - init_timer() was eliminated in 4.15, and all callers were
+   converted to using timer_setup(). The callback prototype has
+   also changed to pass a timer_list argument instead of callback
+   data, and from_timer() must be used to get to the object in
+   which the timer is embedded.
+
+ - usb_get_status() was changed to take an additional argument,
+   and usb_get_std_status() was added as a wrapper for callers to
+   use as a replacment. Call the wrapper in 4.15 and later.
+
+LP: #1737749
