kbuild, gpio: remove MODULE_LICENSE in non-modules 2023-03-06T09:57:49+00:00 Nick Alcock nick.alcock@oracle.com 2023-02-17T14:10:55+00:00 70e1114eb72591cdd493b44c6437f9e11cff81b8 Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message.
