A few update suggestions were taken into account
from static source code analysis.

Markus Elfring (7):
  Delete an error message for a failed memory allocation in ov2640_probe()
  Improve a size determination in ov2640_probe()
  Delete an error message for a failed memory allocation in ov6650_probe()
  Delete an error message for a failed memory allocation in ov9640_probe()
  Improve a size determination in ov9640_probe()
  Delete an error message for a failed memory allocation in ov9740_probe()
  Improve a size determination in ov9740_probe()

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
