[2/5] : OMAP_VOUT: CLEANUP: Remove redundant code from omap_vout_isr
Commit Message
Currently, there is a lot of redundant code is between DPI and VENC panels, this
can be made common by moving out field/interlace specific code to a separate
function called omapvid_handle_interlace_display(). There is no functional
change made.

[Hiremath, Vaibhav] You should check whether fid == 0 before resetting it.

[Hiremath, Vaibhav] This is not matching with the original code, probably I have to be more careful here. I need to spend more time here...

Have you tested TV out functionality?

[Hiremath, Vaibhav] Overall this clean-up was required, thanks for working on this patch.

If you do a dry run of it you'll see that it does the same thing
functionally. If fid was 1, vout->field_id would have been 0 anyway.
So the check for fid == 0 looked a bit redundant to me. However, if you
think that doing this makes the code less clear, we can surely keep this
check.

I haven't checked it yet to be totally honest. Its hard to find a VENC
TV! I wanted to anyway get some kind of Ack from you before starting to
test this. Since you also feel that this clean up is needed, I'll start
testing this out :)

I tested the TV out functionality. It works fine. I have left the extra
fid == 0 check so that the code is more clear. Will post out the new
patch soon.
