Subject: [PATCH] uml: audio: fix -Wmissing-variable-declarations
Date: Tue, 08 Aug 2023 10:21:27 -0700 [thread overview]
Message-ID: <20230808-um_hostaudio-v1-1-3d40fbe1fb1e@google.com> (raw)
I'm looking to enable -Wmissing-variable-declarations behind W=1. 0day
bot spotted the following instance:
arch/um/drivers/hostaudio_kern.c:316:3: warning: no previous extern
declaration for non-static variable 'module_data'
[-Wmissing-variable-declarations]
} module_data;
^
arch/um/drivers/hostaudio_kern.c:313:1: note: declare 'static' if the
variable is not intended to be used outside of this translation unit
struct {
^
This symbol is not referenced by more than one translation unit, so give
it static storage.
