Subject: [PATCH] linux/vt_buffer.h: allow either builtin or modular for macros
Date: Tue, 28 Mar 2023 19:15:29 -0700 [thread overview]
Message-ID: <20230329021529.16188-1-rdunlap@infradead.org> (raw)
Fix build errors on ARCH=alpha when CONFIG_MDA_CONSOLE=m.
This allows the ARCH macros to be the only ones defined.
In file included from ../drivers/video/console/mdacon.c:37:
