prom_putchar() is used centrally in early printk infrastructure therefore at least MIPS should agree on the function return type. [paul.burton@mips.com: - Include linux/types.h in asm/setup.h to gain the bool typedef before we start include asm/setup.h elsewhere. - Include asm/setup.h in all files that use or define prom_putchar(). - Also standardise on signed rather than unsigned char argument.] Signed-off-by: Alexander Sverdlin <alexander.sverdlin@nokia.com> Signed-off-by: Paul Burton <paul.burton@mips.com> Patchwork: https://patchwork.linux-mips.org/patch/19842/ Cc: linux-mips@linux-mips.org Cc: Ralf Baechle <ralf@linux-mips.org> Cc: James Hogan <jhogan@kernel.org> Cc: Jonas Gorski <jonas.gorski@gmail.com> Cc: Florian Fainelli <f.fainelli@gmail.com> Cc: Kate Stewart <kstewart@linuxfoundation.org> Cc: Philippe Ombredanne <pombredanne@nexb.com>
