Subject: libata: wrong sizeof for BUFFER
From: Fiodor Suietov <fiodor.f.suietov@xxxxxxxxx>
I have reproduced the AE_AML_BUFFER_LIMIT exception mentioned in
<http://bugzilla.kernel.org/show_bug.cgi?id=7689> basing on the SSDT ASL
code and libata ata_acpi_push_id() code. There is an oversight in
ata_acpi_push_id() causing the exception. The following update fixes it:
