Subject: [PATCH v5 03/13] module: Make internal.h more compliant
Date:   Wed,  9 Feb 2022 17:03:48 +0000
Message-Id: <20220209170358.3266629-4-atomlin@redhat.com>

This patch will address the following warning and style violations
generated by ./scripts/checkpatch.pl:

  WARNING: Use #include <linux/module.h> instead of <asm/module.h>
  #10: FILE: kernel/module/internal.h:10:
  +#include <asm/module.h>

  CHECK: spaces preferred around that '-' (ctx:VxV)
  #18: FILE: kernel/module/internal.h:18:
  +#define INIT_OFFSET_MASK (1UL << (BITS_PER_LONG-1))
						   ^
  CHECK: extern prototypes should be avoided in .h files
  #84: FILE: kernel/module/internal.h:84:
  +extern int mod_verify_sig(const void *mod, struct load_info *info);

Note: Fortunately, the multiple-include optimisation found in
include/linux/module.h will prevent duplication/or inclusion more than
once.

Fixes: f314dfea16a ("modsign: log module name in the event of an error")
