From 9b5a18e19f8c610c270ee9a0ba03177d737f6aa5 Mon Sep 17 00:00:00 2001 From: Sergei Shtylylov Date: Mon, 13 Oct 2008 21:39:30 +0200 Subject: [PATCH] sgiioc4: fix messages Fix several issues with the log messages printed by ide_dma_sgiioc4() and sgiioc4_ide_setup_pci_device(): - IOC4 registers are memory-mapped but the "BM-DMA at" format corresponds to I/O mapped registers; - "%p" format specifiers and type casts used to print non-pointer values; - using KERN_INFO log level for the error message; - 'hwif->name' printed as drive's name. While at it, also: - return more fitting -EBUSY if request_mem_region() fails; - make the error message style consistent; - fix indentation, put the printk() facility and message on the same line; - use comparisions with NULL instead of ! operator..
