Subject: [PATCH 2/2] ide: remove IDE_HFLAG_CY82C693 host flag
Date: Wed, 20 Feb 2008 21:33:19 +0100 [thread overview]
Message-ID: <200802202133.19126.bzolnier@gmail.com> (raw)
Sergei suggested that it shouldn't be necessary + it had no effect
anyway since ide_id_dma_bug() is called earlier in ide_tune_dma().

I went ahead since I urgently needed to re-cycle one host flag.
