[media] gsc-m2m: Use an unsigned data type for a variable
The data type "int" was used by the variable "ret" in the
gsc_m2m_poll() function despite of the aspect that the type "unsigned int"
will usually be needed for the return value from a call of the
v4l2_m2m_poll() function.
Improve this implementation detail by addition of the type modifier then.
This issue was detected by using the Coccinelle software.
