[PATCH v2] staging: most: video: use min_t() for comparison and assignment

From: Deepak R Varma
Date: Sun Nov 06 2022 - 23:20:59 EST


Simplify code by using min_t helper macro for 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.
