w1: Remove unneeded use of assert() and remove w1_log.h

2017-04-08T16:20:57+00:00

The only use of assert() is in matrox_w1.c and is used to check the input
to probe() from the PCI subsystem for NULL values, these are guaranteed
to be populated and no other PCI driver makes this check, remove this.

As this was the only definition in w1_log.h, remove this also.

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:29+00:00

We are going to split  out of , which
will have to be picked up from other headers and a couple of .c files.

Create a trivial placeholder  file that just
maps to  to make this patch obviously correct and
bisectable.

Include the new header in the files that are going to need it.

w1: Fixup source file headers

2017-01-25T10:48:03+00:00

Remove filename from file, this is not done anymore as it doesn't
add anything and usually is incorrect as filename change often.

Also shorten the GPL to the more common address-less version and
remove excess white-space.

w1: don't leak refcount on slave attach failure in w1_attach_slave_device()

2017-01-25T10:46:42+00:00

Near the beginning of w1_attach_slave_device() we increment a w1 master
reference count.
Later, when we are going to exit this function without actually attaching
a slave device (due to failure of __w1_attach_slave_device()) we need to
decrement this reference count back.

w1: add DS2405 addressable switch driver

2017-01-25T10:46:42+00:00

This adds a driver for a DS2405 1-wire single-channel addressable switch.
The DS2405 can also work as a single-channel binary remote sensor.

This driver supports two attributes: "state" and "output" which are the
same attribute names as supported by existing DS2406, DS2408 and DS2413
drivers.
