This patch also replaces %08llx with %08zx for printing resource start address. Old format was triggering: warning: format ‘%08llx’ expects type ‘long long unsigned int’, but argument 2 has type ‘resource_size_t’ Signed-off-by: Rafał Miłecki <zajec5@gmail.com> --- drivers/mtd/nand/pasemi_nand.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-)
