[PATCH v7 0/2] Add support for LTR-301 and LTR-559 sensors

[Daniel Baluta <daniel.baluta@intel.com>]

This patchset adds support for LiteOn LTR301 ambient light sensor
and LTR559 ambient light and proximity sensor.

v7:
1. Rebase LTR-301 on top of LTR-559 and merged the patches into a single patchset
2. Moved ltr501_chip_info_tbl below ltr501_info in patch 1 in order
to make patch 2 changes look natural. :)
3. Moved "else" branch of id check from patch 2 to patch 1. Now it is no
longer possible to have a NULL name after this check. If id is not NULL
than id->name is one of ltr501_id already defined strings.

v6:
1. Changed the title in commit log

v5:
1. Rebased this patch on top of Daniel's LTR559 patchset
   (http://marc.info/?l=linux-kernel&m=142779827617036&w=2)
2. Added info and channel members to chip_info struture.

v4:
1. Addressed minor comments from Peter Meerwald
2. Changed invalid chip id errno from ENOSYS to ENODEV
3. Fixed channel id index number
4. Removed unused variable.

v3:
1. Sent v2 before by mistake. So sending the final version of v2 as v3.

v2:
1. Handled device id NULL case in probe
2. Changed pr_warn to dev_warn

v1:
Extended LTR501 driver to support both LTR301 and LTR501 device.
