dev_request_mem_region returns a void * which shall be checked with IS_ERR(), but in some cases the valid pointer returned clashes with error values. This is especially the case on some Atmel SoCs. This introduces dev_request_mem_resource which returns a struct resource instead which in any case can be checked with IS_ERR(). It's the drivers responsibility then to get the IOMEM pointer from the resource. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> |
