Subject: tdfxfb: do not make changes to default tdfx_fix
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3b25613c276d390d1dd1d69f238ee779611ccc6c;p=openwrt%2Fstaging%2Fblogic.git

tdfxfb: do not make changes to default tdfx_fix

This was suggested by Geert Uytterhoeven to avoid overwriting of default
values from the tdfx_fix.
