X-Git-Tag: v2.6.15-rc1~529
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f73195ad7e68fb4e546350222d31e19ebc1d3578;p=linux-2.6

[PATCH] matroxfb: Set maxhipri to 0

The current init code sets hiprilvl to 0 and maxhipri to 5.  According to the
specs those values are illegal on both G200 and G400.  It also causes
distortions on the TV-out at least when CRTC2 is in YUV mode as is the case
with DirectFB.  This patch resets both values to 0.
