[PATCH 1/5] gma500: fix a missing break in oaktrail_crtc_mode_set

[Xiaomeng Tong]

Instead of exiting the loop as expected when an entry is found, the
list_for_each_entry() continues until the traversal is complete. It
will certainly lead to a invalid reference to list itereator variable
'connector' after the loop pointing an bogus address at an offset
from the list head, and could lead to multiple 'is_*' flags being set
with true mistakely too.

The invalid reference to list itereator is here:
	drm_object_property_get_value(&connector->base,

To fix this, when found the entry, add a break after the switch
statement.
