From 6691402313ddda232e6a401af8841b5fe676a62f Mon Sep 17 00:00:00 2001 From: Tal Shorer Date: Tue, 16 Aug 2016 19:04:47 +0300 Subject: usb: ulpi: add new api functions, {read|write}_dev() Add these two new api callbacks to struct ulpi_ops. These are different than read, write in that they pass the parent device directly instead of via the ops argument. They are intended to replace the old api functions. If the new api callbacks are missing, revert to calling the old ones as before.
