wan: ixp4xx_hss: fix compile-testing on 64-bit
Change the driver to use portable integer types to avoid warnings during compile testing: drivers/net/wan/ixp4xx_hss.c:863:21: error: cast to 'u32 *' (aka 'unsigned int *') from smaller integer type 'int' [-Werror,-Wint-to-pointer-cast] memcpy_swab32(mem, (u32 *)((int)skb->data & ~3), bytes / 4); ^ drivers/net/wan/ixp4xx_hss.c:979:12: error: incompatible pointer types passing 'u32 *' (aka 'unsigned int *') to parameter of type 'dma_addr_t *' (aka 'unsigned long long *') [-Werror,-Wincompatible-pointer-types] &port->desc_tab_phys))) ^~~~~~~~~~~~~~~~~~~~ include/linux/dmapool.h:27:20: note: passing argument to parameter 'handle' here dma_addr_t *handle); ^ Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
