From 8942939a6c83f34615de5ae041cc9ca846923f94 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 19 Mar 2009 14:14:17 -0700 Subject: USB: gadget: composite device-level suspend/resume hooks Address one open question in the composite gadget framework: Yes, we should have device-level suspend/resume callbacks in addition to the function-level ones. We have at least one scenario (with gadget zero in OTG test mode) that's awkward to handle without it.
