It can happen if a previous conversion was aborted the ADC pulls down the R̅D̅Y̅ line but the event wasn't handled before. In that case enabling the irq might immediately fire (depending on the irq controller capabilities) and even with a rdy-gpio isn't identified as an unrelated one. To cure that problem check for a pending event before the measurement is started and clear it if needed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
