From e7011bf87d6dc3ac045bd3d0a73a9e520974adcf Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Wed, 27 Sep 2023 09:26:48 +0200 Subject: [PATCH] fbdev/gbefb: Initialize fb_ops to fbdev I/O-memory helpers Initialize the instance of struct fb_ops with fbdev initializer macros for framebuffers in I/O address space. Set the read/write, draw and mmap callbacks to the correct implementation and avoid implicit defaults. Also select the necessary I/O helpers in Kconfig. Fbdev drivers sometimes rely on the callbacks being NULL for a default implementation to be invoked; hence requiring the I/O helpers to be built in any case. Setting all callbacks in all drivers explicitly will allow to make the I/O helpers optional. This benefits systems that do not use these functions. No functional changes.
