can: af_can: give struct holding the CAN per device receive lists a sensible name

marckleinebudde · marckleinebudde · commit ff847ee47be2 · 2018-01-05T11:12:08.000+01:00
This patch adds a "can_" prefix to the "struct dev_rcv_lists" to better
reflect the meaning and improbe code readability.

The conversion is done with:

	sed -i \
		-e "s/struct dev_rcv_lists/struct can_dev_rcv_lists/g" \
		net/can/*.[ch] include/net/netns/can.h
