Subject: [PATCH] MIPS: Add prototypes for plat_post_relocation() and relocate_kernel()
Date: Wed, 03 Apr 2024 14:26:33 -0700 [thread overview]
Message-ID: <20240403-mips-kaslr-missing-prototypes-v1-1-26b2390c1b7a@kernel.org> (raw)
When building malta_defconfig with CONFIG_RELOCATABLE=y, there are two
warnings due to missing prototypes for functions only used when that
configuration is enabled:
arch/mips/kernel/relocate.c:42:12: warning: no previous prototype for 'plat_post_relocation' [-Wmissing-prototypes]
42 | int __weak plat_post_relocation(long offset)
| ^~~~~~~~~~~~~~~~~~~~
arch/mips/kernel/relocate.c:324:14: warning: no previous prototype for 'relocate_kernel' [-Wmissing-prototypes]
324 | void *__init relocate_kernel(void)
| ^~~~~~~~~~~~~~~
While relocate_kernel() is only called from assembly, it makes sense to
keep the prototypes together in C to fix the warnings. Add them to
silence the warnings.
