From e0066c4ea9ffa420cb79814411ff74fdc7b7d98e Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Thu, 1 May 2008 04:10:02 +0400 Subject: [PATCH] Fix ACPI vs proc_create_data() mismerge acpi_device_dir() is NULL until all files are createst, so everyting is created in straight in /proc/ and creation code warns.
