From a1d78c16bd31a715785e21967ac6110b386a3c1f Mon Sep 17 00:00:00 2001 From: Sarah Sharp Date: Wed, 9 Dec 2009 15:59:03 -0800 Subject: USB: xhci: Allow allocation of commands without input contexts. The xhci_command structure is the basic structure for issuing commands to the xHCI hardware. It contains a struct completion (so that the issuing function can wait on the command), command status, and a input context that is used to pass information to the hardware. Not all commands need the input context, so make it optional to allocate. Allow xhci_free_container_ctx() to be passed a NULL input context, to make freeing the xhci_command structure simple.
