From 1143832eca8f1d64da7d85642c956ae9d25c69e1 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 6 Jun 2013 10:32:00 -0700 Subject: USB: serial: ports: add minor and port number The usb_serial_port structure had the number field, which was the minor number for the port, which almost no one really cared about. They really wanted the number of the port within the device, which you had to subtract from the minor of the parent usb_serial_device structure. To clean this up, provide the real minor number of the port, and the number of the port within the serial device separately, as these numbers might not be related in the future. Bonus is that this cleans up a lot of logic in the drivers, and saves lines overall.
