[Qemu-devel] [PATCH for-3.0 1/2] armv7m_nvic: Fix m-security subsection name

[Peter Maydell <peter.maydell@linaro.org>]

The vmstate save/load code insists that subsections of a VMState must
have names which include their parent VMState's name as a leading
substring.  Unfortunately it neither documents this nor checks it on
device init or state save, but instead fails state load with a
confusing error message ("Missing section footer for armv7m_nvic").

Fix the name of the m-security subsection of the NVIC, so that
state save/load works correctly for the security-enabled NVIC.
