Looking at it with a nights sleep, it's obvious the code path in
aux_native_write is ok. Is this a bit cleaner than the last patch?
Looks pretty good. I was thinking of something more like this (sorry
for the lack of a patch, I'm away from my source trees at the moment):
while (1) {
ret = radeon_process_aux_ch(dig_connector->dp_i2c_bus,
msg, msg_bytes, recv, recv_bytes, delay,&ack);
if (ret< 0)
return ret;
if ((ack& AUX_NATIVE_REPLY_MASK) == AUX_NATIVE_REPLY_ACK)
return ret;
else if ((ack& AUX_NATIVE_REPLY_MASK) == AUX_NATIVE_REPLY_DEFER)
udelay(400);
else if (ret == 0)
return -EPROTO;
else
return -EIO;
}
Thanks for tracking this down.
