[ Upstream commitde10ac4759] meson_saradc's irq handler uses priv->regmap so make sure that it is allocated before the irq get enabled. This also fixes crash when CONFIG_DEBUG_SHIRQ is enabled, as device managed resources are freed in the inverted order they had been allocated, priv->regmap was freed before the spurious fake irq that CONFIG_DEBUG_SHIRQ adds called the handler.

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 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.
