Did I cause a regression with my patch, without this change? If so, this should be
marked

Cc: stable@...r.kernel.org
Fixes: c9ee94965dce ("ARM: imx: deconstruct mxc_rnga initialization")

and the patch applied ASAP.

It would be nice to add "|| COMPILE_TEST here", but that should probably be
a separate patch, as we don't want to backport that or treat it as a bugfix.
