[PATCH v4 00/26] staging: iio: tsl2583: move out of staging

[Brian Masney <masneyb@onstation.org>]

This patch set continues my work to clean up the tsl2583 driver to move
it out of staging. Some highlights include:

- Eliminated some unnecessary i2c calls to the sensor.
- Fixed issue with changes to calibscale and int_time not being set on
  the chip.
- Moved from a global lux table to a per device lux table.
- Combined redundant sysfs ABI documentation.
- Made log messages clearer.
- Fixes for some return values that were not checked.
- Chip state is now represented as a boolean instead of a tristate.
- Removed unnecessary chip status checks.
- Use a unified prefix for all symbols (tsl2583_).
- Code style and formatting cleanups.
- Comment cleanups.
- Staging graduation.

I verified that the driver functions correctly using a TSL2581 hooked
up to a Raspberry Pi 2.

Changes from V3 to V4
- Fixed patch 03/28 so that it compiles properly. It was fixed later
  in the old series but this needs to be corrected so that people can
  use git bisect. I verified that every patch in this series compiles
  when incrementally applied.
- Clarified comment on patch 14 in this series.
- Use sizeof(value[1]) instead of sizeof(unsigned int) when updating
  the lux table on patch 18 of this series.

Changes from V2 to V3
- Fixed patch #09 to use "%s: <message>", __func__ consistently. Added
  missing terminating "\n" to one of the log messages. Issues reported
  by Joe Perches.
- Fixed issues found by Jonathan Cameron: comment cleanups, improved the
  wording of two log messages, removed an unnecessary memset call,
  removed unnecessary variable initialization, and multiple driver
  authors can be specified with multiple calls to MODULE_AUTHOR().
- Fixed warning found by make C=1 in the per device lux table:
  warning: Variable length array is used.

Changes from V1 to V2
- The first 7 patches in this series contains version 2 of the patches
  7-9 that I sent out on 2016-11-03. The only change is that the patches
  are split up further to make the code review easier.
