From 22835b807e7ca946a4d1fbd4c7af56aa09cd273e Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Fri, 17 Oct 2014 12:05:12 -0500 Subject: usb: gadget: remove unnecessary 'driver' argument now that no UDC driver relies on the extra 'driver' argument to ->udc_stop(), we can safely remove it. This commit is based on previous work by Robert Baldyga which can be found at [1]; however that patch turned out to have a high probability of regressing many UDC drivers because of a blind search & replace s/driver/$udc->driver/ which caused the 'driver' argument to stop_activity() to be a valid non-NULL pointer when it should be NULL, thus causing UDCs to mistakenly call gadget driver's ->disconnect() callback.
