[PATCH 4.4 171/312] [media] am437x-vpfe: fix an uninitialized variable bug

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit e4bccada44c177cde31b9a236b7dfd7f76d403ed upstream.

If we are doing V4L2_FIELD_NONE then "ret" is used uninitialized.

Fixes: 417d2e507edc ('[media] media: platform: add VPFE capture driver support for AM437X')
