The original fix "spi: stm32: Rate-limit the 'Communication suspended' message"
still leads to "stm32h7_spi_irq_thread: 1696 callbacks suppressed" spew in the
kernel log. Since this 'Communication suspended' message is a debug print, add
RATELIMIT_MSG_ON_RELEASE flag to inhibit the "callbacks suspended" part during
normal operation and only print summary at the end.

[1/1] spi: stm32: Print summary 'callbacks suppressed' message
      commit: 195583504be28df5d608a4677dd796117aea875f

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
