In the cleanup path of the MSM DP driver the DP driver's debugfs files are destroyed by invoking debugfs_remove_recursive() on debug->root, which during initialization has been set to minor->debugfs_root. To allow cleaning up the DP driver's debugfs files either each dentry needs to be kept track of or the files needs to be put in a subdirectory which can be removed in one go. By choosing to put the debugfs files in a subdirectory, based on the name of the associated connector this also solves the problem that these names would collide as support for multiple DP instances are introduced. One alternative solution to the problem with colliding file names would have been to put keep track of the individual files and put them under the connector's debugfs directory. But while the drm_connector has been allocated, its associated debugfs directory has not been created at the time of initialization of the dp_debug.
