Subject: asus_acpi: fix a memory leak in asus_hotk_get_info()
From: Axel Lin <axel.lin@gmail.com>

In the case of no match ( hotk->model == END_MODEL ), model sholud be
kfreed before return AE_OK.

This patch includes below fixes:

1. adds a missing kfree(model) before return AE_OK.

2. asus_hotk_get_info should return int, thus return 0 instead of AE_OK.
