From 1d5636cc078d3750b7f590a20f748aeaa26e2daf Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Sun, 10 Dec 2006 02:19:08 -0800 Subject: [PATCH] IPMI: misc fixes Fix various problems pointed out by Andrew Morton and others: * platform_device_unregister checks for NULL, no need to check here. * Formatting fixes. * Remove big macro and convert to a function. * Use strcmp instead of defining a broken case-insensitive comparison, and make the output parameter info match the case of the input one (change "I/O" to "i/o"). * Return the length instead of 0 from the hotmod parameter handler. * Remove some unused cruft. * The trydefaults parameter only has to do with scanning the "standard" addresses, don't check for that on ACPI.
