From 7b51a70cbf0c9995caf59f7126d251e14a9e0686 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Fri, 24 Oct 2008 06:13:23 -0300 Subject: [PATCH] V4L/DVB (9472): dm1105: fix the misuse of pci_dma_mapping_error pci_dma_mapping_error can't be used for pci_alloc_consistent (pci_dma_mapping_error is for dma_map_single and dma_map_page). pci_alloc_consistent returns NULL if the allocation fails.
