Subject: [PATCH 4.2 061/110] ARM: OMAP1: fix incorrect INT_DMA_LCD

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Aaro Koskinen <aaro.koskinen@....fi>

commit 1bd5dfe41b994a6e793363894befef76626965a9 upstream.

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.
