Based on the design pattern utilized in the CM GCR and L2-sync base address getters implementation the platform-specific code is capable to re-define the getters and re-use the weakly defined initial versions. But since the re-definition is supposed to be done in another source file the interface methods have been globally defined which in its turn causes the "no previous prototype" warning printed should the re-definition is finally introduced. Since without the global declarations the pattern can be considered as incomplete and causing the warning printed, fix it by providing the respective methods prototype declarations in "arch/mips/include/asm/mips-cm.h". Signed-off-by: Serge Semin <fancer.lancer@xxxxxxxxx> --- Note as I mentioned in the previous patch, since the weak implementation of the getters isn't utilized other than as a default implementation of the original methods, we can convert the denoted pattern to a simple __weak attributed methods. Let me know if that would be more preferable. --- arch/mips/include/asm/mips-cm.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/mips/include/asm/mips-cm.h b/arch/mips/include/asm/mips-cm.h index 1f143dfad7a2..6dbe74dc323d 100644 --- a/arch/mips/include/asm/mips-cm.h +++ b/arch/mips/include/asm/mips-cm.h @@ -32,6 +32,7 @@ extern void __iomem *mips_cm_l2sync_base; * name mips_cm_phys_base (without underscores). */ extern phys_addr_t __mips_cm_phys_base(void); +extern phys_addr_t mips_cm_phys_base(void); /** * __mips_cm_l2sync_phys_base - retrieve the physical base address of the CM @@ -46,6 +47,7 @@ extern phys_addr_t __mips_cm_phys_base(void); * underscores). */ extern phys_addr_t __mips_cm_l2sync_phys_base(void); +extern phys_addr_t mips_cm_l2sync_phys_base(void); /* * mips_cm_is64 - determine CM register width -- 2.43.0
