From cdee7bdfee37b774c80f698d2d4338670db7c6cb Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Sat, 6 Mar 2010 22:19:53 +0100 Subject: hw/serial.c: fix THRE interrupt clearing UART_IIR_THRI is not a mask, but a possible value for the IIR ID. Use UART_IIR_ID to extract this value. Broken by commit 71e605f80313a632cc6714cde7bd240042dbdd95.
