staging:iio:light:tsl2x7x: fix the error handling in tsl2x7x_probe()

2013-05-22T21:14:57+00:00

Fix to return -EINVAL in the i2c device found error handling
case instead of 0, as done elsewhere in this function.
And also correct the fail1 and fail2 lable to do the right thing.

Pull removal of GENERIC_GPIO from Grant Likely:
 "GENERIC_GPIO now synonymous with GPIOLIB.  There are no longer any
  valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it
  is possible to do so which has been causing confusion and breakage.
  This branch does the work to completely eliminate GENERIC_GPIO."

Pull ARM SoC cleanup from Olof Johansson:
 "Here is a collection of cleanup patches.  Among the pieces that stand
  out are:

   - The deletion of h720x platforms
   - Split of at91 non-dt platforms to their own Kconfig file to keep
     them separate
   - General cleanups and refactoring of i.MX and MXS platforms
   - Some restructuring of clock tables for OMAP
   - Convertion of PMC driver for Tegra to dt-only
   - Some renames of sunxi -> sun4i (Allwinner A10)

Convert selectors of GENERIC_GPIO to GPIOLIB

2013-04-16T09:47:14+00:00

GENERIC_GPIO is now equivalent to GPIOLIB and features that depended on
GENERIC_GPIO can now depend on GPIOLIB to allow removal of this option.

staging:iio:adt7316 Fix some 'interesting' string operations

2013-04-09T17:29:02+00:00

Calling memcmp() to check the value of the first byte in a string is overkill.
Just use buf[0] == '1' or buf[0] != '1' as appropriate.

iio:magnetometer:ak8975 move driver out of staging

2013-04-02T17:36:47+00:00

Issues raised in last series to propose this have now been resolved
so there should be no reason this driver cannot graduate from staging.

staging:iio:magnetometer:ak8975 use standard i2c_smbus read functions.

2013-04-02T17:36:35+00:00

Now the mysterious NOSTART flag is gone from the read, we can use the
i2c_smbus_read_byte/word/i2c_block_data functions instead of the
local reimplementation of these standard functions.

staging:iio:magnetometer:ak8975 drop I2C_M_NOSTART flag in read_data

2013-04-02T17:36:24+00:00

This flag makes no sense whatsoever where it is.
Documentation/i2c/i2c-protocol states:

  If you set the I2C_M_NOSTART variable for the first partial message,
  we do not generate Addr, but we do generate the startbit S. This will
  probably confuse all other clients on your bus, so don't try this.

This is exactly what is going on here.  Likelihood given that the
driver never checked for this protocol mangling being available is that
it wasn't present on the test boards and hence this flag was simply
ignored.  No indication of why it would be necessary has been found in
the datasheets.
