charset="utf-8" The RZ/G3E CRU programs the line stride via the AMnIS register, whose IS field encodes the value in units of 128 bytes. If bytesperline is not a multiple of 128, the division truncates and the hardware uses a wrong stride, causing horizontal banding. Commit ace92ccef0c9 ("media: platform: rzg2l-cru: Use v4l2_fill_pixfmt()") replaced the open-coded aligned calculation with v4l2_fill_pixfmt(), which sets no alignment, reintroducing the issue. Round bytesperline up to RZG2L_CRU_STRIDE_ALIGN and recompute sizeimage when info->has_stride is set. RZ/G2L has no AMnIS register and keeps the values from v4l2_fill_pixfmt() unchanged.
