[media] V4L2: soc-camera: fix uninitialised use compiler warning
In scan_async_group() if the size parameter is negative, the sasd pointer will be used uninitialised: drivers/media/platform/soc_camera/soc_camera.c: In function "soc_camera_host_register": drivers/media/platform/soc_camera/soc_camera.c:1514:55: warning: "sasd" may be used uninitialized in this function [-Wmaybe-uninitialized] sasd->asd.match.i2c.adapter_id, sasd->asd.match.i2c.address); ^ drivers/media/platform/soc_camera/soc_camera.c:1464:34: note: "sasd" was declared here struct soc_camera_async_subdev *sasd; Fix this by making "size" and the array, from which it is assigned unsigned.
