    USB: Core: fix race in device_create · c013d040
    Greg Kroah-Hartman authored
    There is a race from when a device is created with device_create() and
    then the drvdata is set with a call to dev_set_drvdata() in which a
    sysfs file could be open, yet the drvdata will be NULL, causing all
    sorts of bad things to happen.
    
    This patch fixes the problem by using the new function,
    device_create_drvdata().
