I have a different variant of this patch in my local tree, which takes the i2c-core changes that happened in the meantime into account. I'm attaching it to this post if someone want to take a look and/or comment. In fact I think I'll schedule this patch for merge into 2.6.22 regardless of the state of the lm93 driver patch. I'm a bit tired to have to maintain that patch off-tree and to see people waste their time wondering where that function has gone, searching the mailing list for explanations, finding the patch and resubmitting it. We all have better things to do. Anyway, the key point for Hans-J?rgen is: you can assume that function i2c_smbus_read_block_data() will be available to you when your lm93 driver patch is merged upstream. > Jean: I can do the initial review of this one for you when it's ready.
