msm: mdss: fix race condition during mdp debugfs release Fix race condition in the release of the mdp debugfs functions panel_debug_base_release and mdss_debug_base_release by adding the lock for unpreempted freeing of the buffer so that multiple concurrent processes cannot affect the release which can possibly lead to use-after-free operation on the buffer.
