[PATCH] scsi: hpsa: Use min helper for comparison and assignment

From: Deepak R Varma
Date: Sat Jan 28 2023 - 08:47:23 EST


Simplify code by using min_t() helper macro for logical evaluation
and value assignment. Use the _t variant macro since the variable
types are not same.
Proposed change is identified using minmax.cocci semantic patch script.
