[PATCH] libata: wrong sizeof for BUFFER
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: Signed-off-by: Fiodor Suietov <fiodor.f.suietov@intel.com> Cc: Jeff Garzik <jeff@garzik.org> Cc: Tejun Heo <htejun@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
