ACPI: fix resource check message
printk("%pR",...) is for formatting struct resource only. But the list built up in drivers/acpi/osl.c uses it's own struct: struct acpi_res_list {} Without this patch you can see wrongly formatted resources (SMRG is of IO type): ACPI: resource 0000:00:1f.3 [io 0x0400-0x041f] conflicts with AC PI region SMRG [mem 0x00000400-0x0000040f 64bit pref disabled] https://bugzilla.kernel.org/show_bug.cgi?id=26342 Signed-off-by: Thomas Renninger <trenn@suse.de> CC: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Len Brown <len.brown@intel.com>
