The gic_configure_irq(), gic_dist_config(), and gic_cpu_config() functions each take an optional "sync_access" callback, but in almost all cases this is not used. The only user is the GICv3 driver's gic_cpu_init() function, which uses gic_redist_wait_for_rwp() as the "sync_access" callback for gic_cpu_config(). It would be simpler and clearer to remove the callback and have the GICv3 driver call gic_redist_wait_for_rwp() explicitly after gic_cpu_config(). Remove the "sync_access" callback, and call gic_redist_wait_for_rwp() explicitly in the GICv3 driver. There should be no functional change as a result of this patch.

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.
