sata_ahci_read_temperature() is used by sata_ahci_show_temp() also.
So in order to change the function prototype for the get_temp ops which
does not take a void* but a thermal_zone_device* structure, this
function wraps the call.
Do you prefer sata_ahci_read_temperature() becomes sata_ahci_get_temp()
and keep __sata_ahci_read_temperature() name untouched ?
