Without ANON_INODES, we get this build error: drivers/built-in.o: In function `iio_event_getfd': :(.text+0x14bf18): undefined reference to `anon_inode_getfd' All other users explicitly select this symbol, so we should do the same thing here.

The industrial I/O subsystem provides a unified framework for

drivers for many different types of embedded sensors using a

number of different physical interfaces (i2c, spi, etc).

A simple fifo based on kfifo. Note that this currently provides

no buffer events so it is up to userspace to work out how

often to read from the buffer.

Provides IIO core support for triggers. Currently these

This value controls the maximum number of consumers that a
