Subject: [PATCH] platform/x86: dell-smo8800: Use min_t() for comparison and
 assignment

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.
