2012-10-24w1/ds2482: use module_i2c_driver to simplify the codeWei Yongjun1-12/+1
Use the module_i2c_driver() macro to make the code smaller and a bit simpler. dpatch engine is used to auto generate this patch.

2009-10-04ds2482: Discard obsolete detect methodJean Delvare1-30/+5
There is no point in implementing a detect callback for the DS2482, as this device can't be detected. It was there solely to handle "force" module parameters to instantiate devices, but now we have a better sysfs interface that can do the same. So we can get rid of the ugly module parameters and the detect callback. This shrinks the binary module size by 21%.

2008-07-16w1/ds2482: Convert to a new-style driverJean Delvare1-60/+44
The new-style ds2482 driver implements the optional detect() callback to cover the use cases of the legacy driver. I'm curious if anyone really needs this though, so it might be removed in the feature. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2006-07-12[PATCH] w1: fix idle check loop in ds2482Ben Gardner1-1/+1
The idle check loop has a greater-than where it should have a less-than. This causes the ds2482 driver to check for the idle condition exactly once, which causes it to fail on faster machines.
