In order to cooperate with patch 3/3 modification,it is necessary to adjust 
the position where mipi pulls up the signal.

After the patch is applied, the series index (3/3) is disappear, so do
not reference series index in commit description. I think this series
is to adjust the calling sequence, so you could describe as below:

Old sequence:
1. aaa
2. bbb
3. ccc
4. ddd

New sequence:
1. bbb
2. aaa
3. ddd
4. ccc

and this patch is to adjust 'aaa' and 'bbb'.

Regards,
CK
