[PATCH] drm: omapdrm: displays: panel-dsi-cm: Fix field access before set

[Laurent Pinchart]

The driver accesses the ddata->in field before it gets set in the
dsicm_connect() function. Use the local in pointer variable instead.

Tomi,

This patch fixes a bug in a commit from your omapdrm-next branch that
hasn't been merged upstream yet. I'll let you decide whether you want to
squash it with the offending commit (and thus rebase) or apply it on
top. Sorry for screwing up :-/
