debugfs: add missing #ifdef HAS_IOMEM
"debugfs: add tools to printk 32-bit registers" adds new functions which rely on IOMEM functionality which is not present on all architectures and therefore result in compile errors: fs/debugfs/file.c: In function 'debugfs_print_regs32': fs/debugfs/file.c:561:7: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration] Add an #ifdef CONFIG_HAS_IOMEM to fix this Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Acked-by: Alessandro Rubini <rubini@gnudd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
