Subject: [PATCH] hwrng: stm32 - reuse clock rate in stm32_rng_clock_freq_restrain()
Date: Thu, 1 Oct 2026 23:16:10 +0200 [thread overview]
Message-ID: <20261001211612.38124-2-blum@kernel.org> (raw)
Reuse clock_rate and avoid calling clk_get_rate() again. Remove the
extra space before the colon while at it.
Signed-off-by: Thorsten Blum <blum@kernel.org>
