But this warning is not caused by uninitialized timer in either
of matroxfb_DAC1064.c or matroxfb_Ti3026.c, it is caused by reverted
patch to drivers/video/fbcon.c (which was already posted here).

cursor.timer inside matrox_fb_info structure is initialized in
drivers/video/matrox/matroxfb_base.c, in matroxfb_probe function.

So please drop these both patches, to matroxfb_DAC1064.c and
matroxfb_Ti3026.c. They do nothing good, they only cause
init_timer() to be invoked from timer handler itself, and besides that
it fixes nothing, I think that it is also really dangerous thing...

Is my code really so hard to read, that people find nonexistant
uninitialized timers in both ncpfs and matroxfb?
