From 41e7a72e1d3ca62560ec1ef1f4529e7a4c4ad8a3 Mon Sep 17 00:00:00 2001 From: Wyes Karny Date: Tue, 23 May 2023 16:18:15 +0000 Subject: [PATCH] acpi: Replace struct acpi_table_slit 1-element array with flex-array struct acpi_table_slit is used for copying System Locality Information Table data from ACPI tables. Here `entry` is a flex array but it was using ancient 1-element fake flexible array, which has been deprecated. Replace it with a C99 flexible array.
