[PATCH] DA850 EVM: kill useless variable

[Sergei Shtylyov]

Commit 75e2ea643fe43d5aa836475acee5bd97cd9ea4bf (davinci: DA850/OMAP-L138 EVM
expander setup and UI card detection) introduced a useless variable: it's
always set to 1 before it's checked in da850_evm_setup_nor_nand()...

Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com>

---
The patch is against the recent DaVinci tree. It has only been build-tested as
I don't have DA850 EVM board...

Added this patch in queue for 2.6.39. Added a "davinci: " prefix to
the subject line.

Thanks,
