Instead of exiting the loop as expected when an entry is found, the list_for_each_entry() continues until the traversal is complete. It could result in multiple 'is_*' flags being set with true mistakely.
To fix this, when found the entry, add a break after the switch statement.

This patch doesn't apply for me and needs to be rebased on top of drm-misc-next or drm-tip.
On Poulsbo there should only be one encoder per crtc so this is only a theoretical issue. But it is good practice to exit the loop early if we can so the patch still makes sense.
Also, please use the correct subject prefix: drm/gma500: instead of just gma500:.
I will resend another patch as you suggested, thank you.
