Here we have a big rework done by Heikki Krogerus (thanks) which
splits OTG functionality away from transceivers. We have known for quite a long time that struct otg_transceiver was a bad name for the structure, considering transceiver is far from being OTG-specific (see4e67185
). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJPTeeMAAoJEIaOsuA1yqRE6ZAP/j2G6DaDyng6vpyYQi2drXaY NKx3pA0sC98NACOv6sh+urcMDcDctLmOnwV18U+GNNP+qExQFnyuc7iGsXRxfUOj qkIbVPxzPcE0opmEMFJ5ZT85rw33DqKjFnQT4av3wwXe/qSrEkAfBoBSb6wn73rA v0JOhceGsFb+kJAc7U9Ji9A9xSjj+6uw08RTuuQv8KBLb5Pws+NoQ6UEjlni8umA lkOSelyBZN1OJU+fZKIpS4+SiwtdkZCm2wSIUiwaPosdJgw0w8fz0zNjn/4gAHB1 oPyjjjP3/VDegp9CuYDRlnBgQa2K4V1vbjrBfhKbyar8fsOSoaPVv1fR9VKgVnT8 RKlXKSeFEsdP4fOGYCjNKAzjeQH/qSNzdzo+s4GMqoWq7Lm3+b56zdQWvRmTT7Xg ++bMqFAi0noeU8aZWwSDMFiYv6O19o+Px4OTS/3aRmR1wdJpUUSk2M7Quw6A/YNj 4Q5hDvio2eYtI1nya9yMS/j4ZiJ5fDQb5jUfBDB1MKtkZKKzVVSboK8P/rFq5+xf xdUfBRd7/fMk+he6RtemfjhMdYTiX6Cm6VzveZVBL4+7dERbnJDRgDhSJOYvA/eW Bvc7BY+/EYz7msF0gjLyWu3BBiChajk/D5ukoCIssUPGuIhmO1S7JRi1s+fLaNs3 Bz8Haxql69YWrNL2ouQf =WiB6 -----END PGP SIGNATURE----- Merge tag 'xceiv-for-v3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB: transceiver changes for 3.4 Here we have a big rework done by Heikki Krogerus (thanks) which splits OTG functionality away from transceivers.
