patch "iio: light: fix kconfig dependency bug for VCNL4035" added to staging-linus

This is a note to let you know that I've just added the patch titled

iio: light: fix kconfig dependency bug for VCNL4035

to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

Subject: iio: light: fix kconfig dependency bug for VCNL4035

When VCNL4035 is enabled and IIO_BUFFER is disabled, it results in the following Kbuild warning:

WARNING: unmet direct dependencies detected for IIO_TRIGGERED_BUFFER
Depends on [n]: IIO [=y] && IIO_BUFFER [=n]
Selected by [y]:
- VCNL4035 [=y] && IIO [=y] && I2C [=y]

The reason is that VCNL4035 selects IIO_TRIGGERED_BUFFER without depending on or selecting IIO_BUFFER while IIO_TRIGGERED_BUFFER depends on IIO_BUFFER. This can also fail building the kernel.

Honor the kconfig dependency to remove unmet direct dependency warnings and avoid any potential build failures.
