Subject: [PATCH 1/2] crypto: jitterentropy - drop redundant delta check in jent_entropy_init
Date: Mon,  4 May 2026 10:28:50 +0200	[thread overview]
Message-ID: <20260504082848.7194-4-thorsten.blum@linux.dev> (raw)

Since start_time = end_time - delta, start_time can only equal end_time
when delta is 0, making the explicit end_time == start_time check
redundant. Remove it.
