Martin Fuzzey 7d46883724 binder: fix log spam for existing debugfs file creation. ... commit eb143f8756 upstream. Since commit 43e23b6c0b ("debugfs: log errors when something goes wrong") debugfs logs attempts to create existing files. However binder attempts to create multiple debugfs files with the same name when a single PID has multiple contexts, this leads to log spamming during an Android boot (17 such messages during boot on my system). Fix this by checking if we already know the PID and only create the debugfs entry for the first context per PID. Do the same thing for binderfs for symmetry.
