Subject: [PATCH 4.9 082/264] random: remove unused irq_flags argument from add_interrupt_randomness()
Date: Thu, 23 Jun 2022 18:41:15 +0200 [thread overview]
Message-ID: <20220623164346.390524772@linuxfoundation.org> (raw)
In-Reply-To: <20220623164344.053938039@linuxfoundation.org>
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
commit 703f7066f40599c290babdb79dd61319264987e9 upstream.
Since commit
ee3e00e9e7101 ("random: use registers from interrupted code for CPU's w/o a cycle counter")
the irq_flags argument is no longer used.
Remove unused irq_flags.
