X-Git-Tag: v2.6.30-rc1~672^2~41
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1f5892a5d21c905b1614cbd6bd8c5ad2cfbc106f;p=pandora-kernel.git

ide-acpi: cleanup do_drive_set_taskfiles()

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

* ide_acpi_exec_tfs() prints sufficient debug info about the
  device so no need to do it again.

* do_drive_get_GTF() + ide_acpi_exec_tfs() make sure that this
  function will never be called with incorrect gtf_length argument
  or if device is not present.
