[PATCH 2/2] UMS: Fix comparison of unsigned variable against < 0.

[Michel Dänzer]

From: Michel Dänzer <daenzer at vmware.com>

Pointed out by clang:

../../src/radeon_crtc.c:242:18: error: comparison of unsigned expression < 0 is always false [-Werror,-Wtautological-compare]
                        error = error < 0 ? 0xffffffff : error;
                                ~~~~~ ^ ~
---

Is this what was intended? And will it work as intended, or cause subtle
regressions? :}
