ring-buffer: Return 0 on success from ring_buffer_resize()
commit 0a1754b2a97efa644aa6e84d1db5b17c42251483 upstream.
We don't need to check the new buffer size, and the return value

...
ret = ring_buffer_resize(trace_buf->buffer,
per_cpu_ptr(size_buf->data,cpu_id)->entries, cpu_id);
if (ret == 0)
per_cpu_ptr(trace_buf->data, cpu_id)->entries =
per_cpu_ptr(size_buf->data, cpu_id)->entries;
