From da13b3361bb609f5e3fde3f57b8e2b42001513a3 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 29 Aug 2022 17:11:28 +0300 Subject: ACPI: LPSS: Replace loop with first entry retrieval After the commit 6505e452371d ("ACPI: LPSS: Use the helper acpi_dev_get_memory_resources()") the list is empty or contains only resource of IORESOURCE_MEM type. Hence, no need to check for the type, and since we break after the first found, no need to iterate over full list. That said, replace loop with first entry retrieval.
