From 9b510df703d282effba4f56ac567aa8011d56e6b Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 1 Jul 2015 20:53:01 +0200 Subject: [PATCH] dm: usb: Rename usb_find_child to usb_find_emul_child Now that we unbind usb devices from usb_stop() usb_find_child() is only necessary to deal with emulated usb devices. Rename it to make this clear and add a #ifdef to make it a nop in other cases. Note the #ifdef turns usb_find_emul_child() into a nop, rather then not building it and adding another #ifdef to the caller, this is done this way because adding a #ifdef to the caller is somewhat hairy.
