In the current implementation, the return value of dev_pm_domain_attach() is not checked. This can lead to silent failures if the function fails, as the code would continue execution and return 0, ignoring the error. This patch adds a check for the return value of dev_pm_domain_attach(). If the function fails, an error message is logged using dev_err_probe(), and the error is propagated to the existing error handling path `err`, which ensures proper cleanup by calling clk_notifier_unregister().

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.
