From a6a241764f69c62d23fc6960920cc662ae4069e9 Mon Sep 17 00:00:00 2001 From: Ross Lagerwall Date: Mon, 11 Sep 2023 11:32:51 +0100 Subject: swiotlb: use the calculated number of areas Commit 8ac04063354a ("swiotlb: reduce the number of areas to match actual memory pool size") calculated the reduced number of areas in swiotlb_init_remap() but didn't actually use the value. Replace usage of default_nareas accordingly.
