Subject: [PATCH v2 10/11] media: sun6i-isp: capture: Fix uninitialized variable use
While the stride_chroma variable was previously initialized to zero,
it's actually stride_chroma_div4 that is set to hardware registers.
Initialize it to zero instead to avoid an uninitialized variable use
and get rid of the associated smatch warning.
