Subject: [PATCH 4/5] ARM: module: fix modsign build error
Patch-mainline: v4.19-rc1
Git-commit: 4d58e7034d1971436d44f203cf69d2feb6b82e5c
References: bsc#1093666

The asm/module.h header file can not be included standalone, which
breaks the module signing code after a recent change:

In file included from kernel/module-internal.h:13,
                 from kernel/module_signing.c:17:
arch/arm/include/asm/module.h:37:27: error: 'struct module' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
 u32 get_module_plt(struct module *mod, unsigned long loc, Elf32_Addr val);

This adds a forward declaration of struct module to make it all work.

Fixes: f314dfea16a0 ("modsign: log module name in the event of an error")
