[libcamera-devel] [PATCH 07/11] ipu3: ipa: agc: Determine cell size from ipu3_uapi_awb_set_item

[Jean-Michel Hautbois]

The kCellSize was hardcoded from the size determined by examining the
statistics from the ImgU.  The cell definition is now described as a
struct. Utilise the struct size to express the cell size.
