fw_cfg: fix sparse warnings in fw_cfg_sel_endianness()
Dispatch to the appropriate iowrite() instead of casting restricted
type to u16.
- if fw_cfg_is_mmio:
before: iowrite16(cpu_to_be16(key))
after: iowrite16be(key)
- if !fw_cfg_is_mmio:
before: iowrite16(cpu_to_le16(key))
after: iowrite16(key)
which is equivalent on little-endian systems, where fw_cfg IO is supported.
Fixes:
$ make C=1 CF=-D__CHECK_ENDIAN__ drivers/firmware/qemu_fw_cfg.o
drivers/firmware/qemu_fw_cfg.c:55:33: warning: restricted __be16 degrades to integer
drivers/firmware/qemu_fw_cfg.c:55:52: warning: restricted __le16 degrades to integer
