charset=UTF-8 Content-Transfer-Encoding: 8bit Use resource_size() instead of open coding res->end - res->start + 1. Include linux/ioport.h explicitly, since the file relies on struct resource and now on the helper as well. Signed-off-by: Aryan Sinha --- v2: elaborate more in the commit message, and include linux/ioport.h. Both as per Rodrigo suggestions.
