Subject: [for-linus][PATCH 5/9] tracing: Drop unneeded assignment in ring_buffer_resize()
Date: Wed, 16 Dec 2020 20:04:13 -0500 [thread overview]
Message-ID: <20201217010502.754824602@goodmis.org> (raw)
In-Reply-To: <20201217010408.742794078@goodmis.org>
From: Lukas Bulwahn <lukas.bulwahn@gmail.com>
Since commit 0a1754b2a97e ("ring-buffer: Return 0 on success from
ring_buffer_resize()"), computing the size is not needed anymore.
Drop unneeded assignment in ring_buffer_resize().
