[i2c] AU1550 I2C driver - why not wait for bus free?

[Sergei Poselenov]

Hello all,

I have a question about AU1550 I2C driver.
Why the driver starts transfer regardless of the state
of I2C bus? Shouldn't it wait for the "bus busy" bit
in smbstat to become zero before setting the
"master start" bit?

I see, in the 2.4 version of the driver the above logic
was present, but avoided in 2.6.

Thanks a lot any help.

Regards,
Sergei
