Subject: mips: decompress: fix add missing prototypes
Date: Mon, 4 Dec 2023 12:56:51 +0100
Patch series "mips: address -Wmissing-prototypes warnings".
Address the -Wmissing-prototypes warnings that showed up in mips as the
last major architecture after my patch to enable the option everywhere.
This patch (of 20):
The mips decompressor has some string functions defined locally that are
not declared in the right place:
arch/mips/boot/compressed/dbg.c:12:13: error: no previous prototype for 'putc' [-Werror=missing-prototypes]
arch/mips/boot/compressed/dbg.c:16:6: error: no previous prototype for 'puts' [-Werror=missing-prototypes]
arch/mips/boot/compressed/dbg.c:26:6: error: no previous prototype for 'puthex' [-Werror=missing-prototypes]
arch/mips/boot/compressed/string.c:11:7: error: no previous prototype for 'memcpy' [-Werror=missing-prototypes]
arch/mips/boot/compressed/string.c:22:7: error: no previous prototype for 'memset' [-Werror=missing-prototypes]
arch/mips/boot/compressed/string.c:32:15: error: no previous prototype for 'memmove' [-Werror=missing-prototypes]
arch/mips/boot/compressed/decompress.c:43:6: error: no previous prototype for 'error' [-Werror=missing-prototypes]
arch/mips/boot/compressed/decompress.c:91:6: error: no previous prototype for 'decompress_kernel' [-Werror=missing-prototypes]
Include the string.h header where needed and add a decompress.h header to
have shared prototypes for the rest.
