[Lcdproc] flaky hd44780

[Pierre Ossman]

Hi,

I have a SilverStone L03v case with a parallell port HD44780 in it which I've had some problem with. Lately, it went completely useless as the data starting shuffling around the display like crazy. After digging through the specs I noticed some scroll feature in the hardware, and it proved to be the problem.

So I'd like you guys to include the following in common_init() of the hd44780 driver:

	p->hd44780_functions->senddata(p, 0, RS_INSTR, ENTRYMODE | E_MOVERIGHT | NOSCROLL);
	p->hd44780_functions->uPause(p, 40);

I've put it just before the CLEAR instruction and it solves the problem here.

Rgds
