[PATCH] ARM: OMAP1: fix incorrect INT_DMA_LCD

[Aaro Koskinen]

Commit 685e2d08c54b ("ARM: OMAP1: Change interrupt numbering for
sparse IRQ") turned on SPARSE_IRQ on OMAP1, but forgot to change
the number of INT_DMA_LCD. This broke the boot at least on Nokia 770,
where the device hangs during framebuffer initialization.

Fix by defining INT_DMA_LCD like the other interrupts.

OK good to hear, applying into omap-for-v4.3/fixes. If it does not get
pulled for v4.3, then it's already tagged cc: stable. BTW, you should
not send mail to cc stable when posting patches, Greg will send you
a note on that.

I'm having hard time booting 770 and n800 after I had to change my motherboard
last sring.

Somehow 0xFFFF can't get anything loaded over USB. I even installed a new
PCIe OHCI + EHCI adapter but still no luck.

Regards,

Tony
