[PATCH 1/2] asus_acpi: fix a memory leask in asus_hotk_get_info

[Axel Lin]

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.

[PATCH 2/2] asus_acpi: fix coding style to improve readability

[Axel Lin]

In the case of no match ( hotk->model == END_MODEL ),
the only posible case to return 0 is to have a Samsung P30 detected.
This patch improves readability by moving related code after if/else clause
to be inside if clause.
