Input: resistive-adc-touch - fix kconfig dependency on IIO_BUFFER
[ Upstream commit 676650d007e06fddcf3fe38238251d71bd179641 ]
When TOUCHSCREEN_ADC is enabled and IIO_BUFFER is disabled, it results
in the following Kbuild warning:
WARNING: unmet direct dependencies detected for IIO_BUFFER_CB
Depends on [n]: IIO [=y] && IIO_BUFFER [=n]
Selected by [y]:
- TOUCHSCREEN_ADC [=y] && !UML && INPUT [=y] && INPUT_TOUCHSCREEN [=y] && IIO [=y]
The reason is that TOUCHSCREEN_ADC selects IIO_BUFFER_CB without depending
on or selecting IIO_BUFFER while IIO_BUFFER_CB 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.
