video: fbdev: atari: Simplify atafb_pan_display()
The fb_pan_display() function in the core already takes care of validating the panning parameters before calling the driver's .fb_pan_display() callback, and of updating the panning state afterwards, so there is no need to repeat that in the driver. Remove the duplicate code. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Tested-by: Michael Schmitz <schmitzmic@gmail.com> Signed-off-by: Helge Deller <deller@gmx.de>
