From dcdbfaafe90a5e6e172368b2aa5500a9ca192e49 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 15 May 2020 17:04:10 +0200 Subject: [PATCH] acpi: move aml builder code for serial device MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The code uses the isa_serial_io array to figure what the device uid is. Side effect is that acpi antries are not limited to port 1+2 any more, we'll also get entries for ports 3+4.
