From 0ec734c2b8b005667ffdaef8610d1024630683b0 Mon Sep 17 00:00:00 2001 From: Wolfgang Ocker Date: Sun, 10 Feb 2008 20:31:33 +0100 Subject: [PATCH] [MIPS] Alchemy: Fix ids in Alchemy db dma device table 0 is a valid device id (DSCR_CMD0_UART0_TX), so we can't use it to mark an empty entry in the device table. Use ~0 instead and search for id ~0 when looking for a free entry.
