[libata] acpi: call ata_acpi_gtm during ata port init time (83400917) · Commits · 戴 / test

Commit mistakenly dropped the code to get an initial gtm for the IDE channel. This caused the following problem for Sergei: http://marc.info/?l=linux-kernel&m=134484963618457&w=2 Fix this by adding the call back in ata_acpi_bind_host, and due to this, the ata_ap_acpi_handle is modified accordingly.
