[PATCH] staging: most: video: use min_t() for comparison and assignment

[Deepak R Varma]

Simplify code by using min_t helper macros in place of lengthy if/else
block oriented logical evaluation and value assignment. Use the _t
variant of min macro since the variable types are not same.
This issue is identified by coccicheck using the minmax.cocci file.
