X-Git-Tag: v2.6.30-rc1~672^2~42
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2f0d0fd2a605666d38e290c5c0d2907484352dc4;p=pandora-kernel.git

ide-acpi: cleanup do_drive_get_GTF()

* ide_noacpi is already checked by ide_acpi_exec_tfs()
  which is the only user of do_drive_get_GTF().

* ide_acpi_exec_tfs() prints sufficient debug info about the
  device so no need to have excessive data about port/host.

* It is sufficient to check for drive->acpidata->obj_handle
  as it will be NULL if dev == NULL or hwif->acpidata == NULL
  or device is not present.
