Hi 06.10.2013, 23:13, "Hans-Frieder Vogt" <[email protected]>: > In recent kernels the 1-wire kernel modules do not work any more. The module > wire got broken in 3.11-rc1 and 3.12-rc1 introduced a further problem:

That's correct > 2: 3.12-rc1 introduced w1_bus_notify which assumes that all slaves have fops > defined. This is not the case for e.g. w1_smem and maybe also breaks custom > written modules. Isn't fops are supposed to be in the slave device? Although they look meaningless for most of devices, I would introduce them everywhere... But anyway, your patches fix those problems, thanks a lot. Greg, please queue them into appropriate trees.
