Subject: drm/tiny/ofdrm: Use fbdev-shmem
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=049f75bd0b0d6464a41ddaf482f0055a45ac055e;p=linux.git

drm/tiny/ofdrm: Use fbdev-shmem

Implement fbdev emulation with fbdev-shmem. Avoids the overhead of
fbdev-generic's additional shadow buffering. No functional changes.
