From cbe606f304ec188b90e0b9f8b3e8b37d57553f81 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Sun, 6 Aug 2023 13:58:54 +0200 Subject: [PATCH] fbdev/sbus: Add initializer macros and Kconfig tokens for SBUS support Add macros to initialize struct fb_ops for drivers that support framebuffers on Sparc's SBUS. Also add a Kconfig token that selects the necessary helpers.
