Subject: nvidiafb: ensure that CRTC registers are accessible
From: "Antonino A. Daplas" <adaplas@xxxxxxxxx>
- Ensure that CRTC registers are accessible by unlocking them on set_par(),
otherwise i2c reading will fail.
- The function nvidia_vga_protect(), does not protect the VGA registers, but
turns off the screen. Rename it to nvidia_screen_off().
