Subject: Input: i8042 - set up shared ps2_cmd_mutex for AUX ports
From: Dmitry Torokhov <[email protected]>
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.
