Data-ready line in LIS3MDL is routed to drdy pin and it is not possible
to select a different INT pin. st_sensors_set_dataready_irq() assumes
that if drdy int address is not exported in register map, irq trigger
is not supported by the sensor and hw_irq_trigger is always false.
Based on this configuration st_sensors_irq_thread does not consume
generated interrupt causing an unhandled irq.
Fix this taking into account status register address in
st_sensors_set_dataready_irq()

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
