Subject: [for-linus][PATCH 5/9] tracing: Drop unneeded assignment in ring_buffer_resize()

From: Lukas Bulwahn <lukas.bulwahn@...il.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().
