Subject: [PATCH] Remove MODULE_ALIAS() calls that take undefined macro
Date: Tue,  7 May 2019 02:28:17 +0900	[thread overview]
Message-ID: <1557163697-17882-1-git-send-email-yamada.masahiro@socionext.com> (raw)

These files do not define (USBHS_)DRIVER_NAME. Yet, they can be
successfully compiled because they are never built as a module by
anyone, i.e, the MODULE_ALIAS() calls are always no-op.

A problem showed up when a patch "moduleparam: Save information about
built-in modules in separate file" is applied. With this new feature,
MODULE_*() are populated even if the callers are built-in.

To avoid the build errors, the lines referencing to the undefined
macro must be removed.

The complete fix is to remove all MODULE_* and #include <linux/module.h>
like many "make ... explicitly non-modular" commits did.

For now, I am touching the offending lines.

I will insert this commit before
