efi: Reorder pr_notice() with add_device_randomness() call
Currently, when we receive a random seed from the EFI stub, we call add_device_randomness() to incorporate it into the entropy pool, and issue a pr_notice() saying we are about to do that, e.g., [ 0.000000] efi: RNG=0x87ff92cf18 [ 0.000000] random: fast init done [ 0.000000] efi: seeding entropy pool Let's reorder those calls to make the output look less confusing: [ 0.000000] efi: seeding entropy pool [ 0.000000] efi: RNG=0x87ff92cf18 [ 0.000000] random: fast init done Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Matt Fleming <matt@codeblueprint.co.uk> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-efi@vger.kernel.org Link: http://lkml.kernel.org/r/20180308080020.22828-11-ard.biesheuvel@linaro.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
