[PATCH v3 2/2] staging: vt6655: use memset to make code clearer

[Nam Cao]

A line of code sets the entire struct vnt_rdes0 to zero by treating it as
unsigned int. This works because sizeof(unsigned int) is equal to
sizeof(struct vnt_rdes0) (4 bytes). However it is not obvious what this
code is doing. Re-write this using memset to make the code clearer.
