+Subject: [PATCH 65/86] ACPI: processor idle: Use swap() instead of open coding
+ it
+
+commit 0e6078c3c6737df7d0bd0c890fbadf24a27fffbb upstream
+
+Address the following coccicheck warning:
+
+./drivers/net/ethernet/mellanox/mlx5/core/en/tc_ct.c:914:40-41:
+WARNING opportunity for swap().
+
+by using swap() for the swapping of variable values and drop
+the tmp variable that is not needed any more.
