| |
3.16.39-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
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.
