file_operations are accessed only via debugfs_create_file(), so
debugfs wrappers will take care of that itself.
2) kmalloc() for a buffer used only for duration of a function is not
a problem, but for a buffer no longer than 16 bytes?
3) strstr() is for finding substrings; for finding a character there's
strchr().

Powering-off a genpd that was on during boot, before all of its consumer
devices have been probed, is certainly prone to problems.
For OF based platforms we can rely on using the sync_state mechanism that
the fw_devlink provides, to understand when all consumers for a genpd
provider have been probed. Let's therefore prevent these genpds from being
powered-off until the ->sync_state() callback gets called.
Note that, for non-OF based platform we will keep relying on the
late_initcall_sync, which seems to be the best we can do for now.

'struct meson_secure_pwrc_domain_data' are not modified in these drivers.
Constifying these structures moves some data to a read-only section, so
increases overall security.

Renesas Kconfig is using "SoC chip number" for CONFIG symbol, but is
using "SoC chip name" for menu description. Because of it, it looks
random order when we run "make menuconfig".
commit 6d5aded8d5 ("soc: renesas: Sort driver description title")
sorted Renesas Kconfig by "menu description title order" (= SoC chip
name), but it makes confusable to add new config, because developer
usually checks CONFIG symbols (= SoC chip number).
Let's indicate both "SoC chip number" and "SoC chip name" in description
and sort it again.
