cyber2000fb: fix machine hang on module load
I was testing two CyberPro 2000 based PCI cards on x86 and the machine always hanged completely when the cyber2000fb module was loaded. It seems that the card hangs when some registers are accessed too quickly after writing RAMDAC control register. With this patch, both card work. Add delay after RAMDAC control register write to prevent hangs on module load. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
