Subject[PATCH v3 2/2] staging: media: ipu3: fixing stripe1 x_end is greater than BDS width
Date
If both stripes are enabled, an improper AF grid configuration leads
the AF scene width to be wilder than the BDS width. Also, the second
stripe x_end is estimated based on the remaining AF scene width.
Therefore, the second stripe x_end will be greater than the second
stripe BDS width.

In this patch, if the second stripe x_end is greater than BDS width,
x_end will be set to BDS width.
