libfdt: Several cleanups to parameter checking
This patch makes a couple of small cleanups to parameter checking of libfdt functions. - In several functions which take a node offset, we use an idiom involving fdt_next_tag() first to check that we have indeed been given a node offset. This patch adds a helper function _fdt_check_node_offset() to encapsulate this usage of fdt_next_tag(). - In fdt_rw.c in several places we have the expanded version of the RW_CHECK_HEADER() macro for no particular reason. This patch replaces those instances with an invocation of the macro; that's what it's for. - In fdt_sw.c we rename the check_header_sw() function to sw_check_header() to match the analgous function in fdt_rw.c, and we provide an SW_CHECK_HEADER() wrapper macro as RW_CHECK_HEADER() functions in fdt_rw.c Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
