Re: [PATCH] MSI Megasky 580 GL861 i2c timeout fix (Antti Palosaari)

Fix works great man! I commented the lines out provided by Jonas Larsson and added yours.
Now I can even switch channels faster then before (seems like the do while took to much time).
And it's even easier to fix the gl861 module (cause you just need to add 1 line).
Don't know if you have to change udelay value depending on system speed.

for comparison here my system specs:
Board: MSI K8t Neo Fis2R
CPU: AMD Athlon 64 3,2GHz (running @ 2GHz)
RAM: 1GB

Great work! Best regards, pferdone
