Subject: [PATCH] module: include internal.h in module/dups.c

From: Arnd Bergmann <[email protected]>

Two newly introduced functions are declared in a header that is not
included before the definition, causing a warning with sparse or
'make W=1':

kernel/module/dups.c:118:6: error: no previous prototype for 'kmod_dup_request_exists_wait' [-Werror=missing-prototypes]
118 | bool kmod_dup_request_exists_wait(char *module_name, bool wait, int *dup_ret)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
kernel/module/dups.c:220:6: error: no previous prototype for 'kmod_dup_request_announce' [-Werror=missing-prototypes]
220 | void kmod_dup_request_announce(char *module_name, int ret)
| ^~~~~~~~~~~~~~~~~~~~~~~~~

Add an explicit include to ensure the prototypes match.

Linus, only one fix so far for modules so might as well send this as a patch.
