Subject: [PATCH] drivers/acpi/acpica/exserial.c: replace ternary operator with min()
Date:   Tue, 28 Mar 2023 09:51:20 +0800

Fix the following coccicheck warning:

drivers/acpi/acpica/exserial.c:346: WARNING opportunity for min().

min() macro is defined in include/linux/minmax.h. It avoids
multiple evaluations of the arguments when non-constant and performs
strict type-checking.
