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: ds2405: use module_w1_family to simplify the code

2017-02-10T14:32:53+00:00

module_w1_family() makes the code simpler by eliminating boilerplate code. Signed-off-by: Wei Yongjun Acked-by: Maciej S. Szmigiero Signed-off-by: Greg Kroah-Hartman

w1: ds2490: use kmemdup rather than duplicating its implementation

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. Signed-off-by: Andrew F. Davis Signed-off-by: Greg Kroah-Hartman

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. Signed-off-by: Maciej S.

w1: ds2490: USB transfer buffers need to be DMAable

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

ds2490 driver was doing USB transfers from / to buffers on a stack. This is not permitted and made the driver non-working with vmapped stacks. Since all these transfers are done under the same bus_mutex lock we can simply use shared buffers in a device private structure for two most common of them. While we are at it, let's also fix a comparison between int and size_t in ds9490r_search() which made the driver spin in this function if state register get requests were failing.

w1: omap_hdq: Free resources on error path

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

In case of error returned by '_omap_hdq_reset()', free resources as done elsewhere in this function. This patch slighly changes the semantic of the code. It now propagates the error code returned by '_omap_hdq_reset()' instead of returning -EINVAL unconditionally.

drivers: w1: style corrections-pointers-blanklines-comparisons

2016-08-31T11:56:04+00:00

Correct pointer notations to include whitespace between variable type and "*" character. Inserted blank line after variable declatations at two locations. Rearranged comparison within an if statment to have the constant on the right-hand side. Signed-off-by: Ben Werbowyj Acked-by: Evgeniy Polyakov Signed-off-by: Greg Kroah-Hartman
