Input: i8042 - set up shared ps2_cmd_mutex for AUX ports
commit 47af45d684b5f3ae000ad448db02ce4f13f73273 upstream. The commit 4097461897df ("Input: i8042 - break load dependency ...") correctly set up ps2_cmd_mutex pointer for the KBD port but forgot to do the same for AUX port(s), which results in communication on KBD and AUX ports to clash with each other. Fixes: 4097461897df ("Input: i8042 - break load dependency ...")
