w1: omap-hdq: fix error return code in omap_hdq_probe()

2017-07-17T14:48:15+00:00

platform_get_irq() returns an error code, but the omap_hdq
driver ignores it and always returns -ENXIO. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error.

Print error message and propagate the return value of
platform_get_irq on failure.

w1: Fix slave count on 1-Wire bus (resend)

2017-07-17T14:45:16+00:00

1-Wire bus have very fast algorith for exchange with single slave
device. Fix incorrect count of slave devices on connect second slave
device. This case on slave device probe() step we need use generic
(multislave) functions for read/write device.

w1: Add subsystem kernel public interface

2017-06-09T09:54:54+00:00

Like other subsystems we should be able to define slave devices outside
of the w1 directory. To do this we move public facing interface
definitions to include/linux/w1.h and rename the internal definition
file to w1_internal.h.

As w1_family.h and w1_int.h contained almost entirely public
driver interface definitions we simply removed these files and
moved the remaining definitions into w1_internal.h.

With this we can now start to move slave devices out of w1/slaves and
into the subsystem based on the function they implement, again like
other drivers.

w1: Organize driver source to natural/common order

2017-05-25T16:23:03+00:00

Structures and functions should be ordered such that forward declaration
use is minimized.

MODULE_* macros should immediately follow the structures and functions
upon which they act.

Remaining MODULE_* macros should be at the end of the file in
alphabetical order.

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.
