From a8d78cd0ab6204b6ee8897e30d0fbb9c8979ddca Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 20 Apr 2018 15:52:42 +0100 Subject: [PATCH] vl.c: Provide accessor function serial_hd() for serial_hds[] array MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Provide an accessor function serial_hd() to return the Chardev (if any) associated with the numbered serial port. This will be used to replace direct accesses to the serial_hds[] array, so that calling code doesn't need to care about the size of that array.
