Merge tag 'w1-drv-7.3' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/krzk/linux-w1 into char-misc-next

Krzysztof writes:

1-Wire bus drivers for v7.3

1. Improve (fix) ds2482 driver module autoloading, when probing from
   Devicetree.

2. Convert HDQ One Wire devicetree bindings to DT schema format.

3. Fixes for handling incorrect data from potentially malicious
   hardware, looking theoretical issues but still worth to fix.
   Affected drivers: w1 core code, ds28e17 and ds2482.

* tag 'w1-drv-7.3' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/krzk/linux-w1:
  w1: ds2482: Fix signedness bug in ds2482_w1_triplet()
  w1: validate slave string length before checking separator
  w1: ds28e17: reject an oversize length on an I2C block read
  dt-bindings: w1: Convert HDQ One Wire to DT schema
  w1: ds2482: add OF device match table

-* OMAP HDQ One wire bus master controller
-
-Required properties:
-- compatible : should be "ti,omap3-1w" or "ti,am4372-hdq"
-- reg : Address and length of the register set for the device
-- interrupts : interrupt line.
-- ti,hwmods : "hdq1w"
-
-Optional properties:
-- ti,mode: should be "hdq": HDQ mode  "1w": one-wire mode.
-	   If not specified HDQ mode is implied.
