Subject: [PATCH] iio: humidity: am2315: Select IIO_TRIGGERED_BUFFER to prevent build errors
Date: Thu, 18 Aug 2016 17:05:18 +0300	[thread overview]
Message-ID: <1471529118-81255-1-git-send-email-mika.westerberg@linux.intel.com> (raw)

Commit 0d96d5ead3f7 ("iio: humidity: Add triggered buffer support for
AM2315") added support for triggered buffers but those are only available
when IIO_TRIGGERED_BUFFER is selected. Currently we get warnings like:

  drivers/iio/humidity/am2315.c: In function ‘am2315_trigger_handler’:
  drivers/iio/humidity/am2315.c:186:2: error: implicit declaration of function
    ‘iio_push_to_buffers_with_timestamp’ [-Werror=implicit-function-declaration]
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  cc1: some warnings being treated as errors
  scripts/Makefile.build:289: recipe for target 'drivers/iio/humidity/am2315.o' failed

Furthermore linking the kernel executable fails because triggered buffer
functions are never build.

Fix this by selecting IIO_TRIGGERED_BUFFER and IIO_BUFFER when the driver is
enabled.

       If you say yes here you get support for the Aosong AM2315
       relative humidity and ambient temperature sensor.
