Subject: include/linux/ioport.h: new helper to define common struct resource constructs
From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>
Resource definitions that just define start, end and flags =
IORESOURCE_MEM or IORESOURCE_IRQ (with start=end) are quite common. So
introduce a shortcut for them. For completeness add macros for
IORESOURCE_DMA and IORESOURCE_IO, too and also make available a set of
macros to specify named resources of all types which are less common.
