From 4232739709060703e9dd6f5d6839c37e008d389d Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Wed, 27 Sep 2023 09:27:01 +0200 Subject: fbdev/pvr2fb: 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.
