commit a37a7c5a1b9310b7bcff0e2c2940e7c87805247f Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Mon Feb 10 00:00:44 2014 +0200
usbdebug: Unify console API
Struct dbgp_pipe would not be suitable for use with xHCI. Just use an index, it is easy to setup in Kconfig if our future debug setup has separate pipes for console output and debugging/traceings.
