Subject: [RFC: 2.6 patch] drivers/pci/pci.c: remove pci_dac_set_dma_mask
Date: Sun, 1 May 2005 15:53:08 +0200 [thread overview]
Message-ID: <20050501135308.GC3592@stusta.de> (raw)
pci_dac_set_dma_mask is currently completely unused.
Is any usage planned in the forseeable future or is this patch to remove
it OK?
