Subject: sh: dma: use __maybe_unused
From: David Rientjes <rientjes@xxxxxxxxxx>
There is no such thing as labeling a variable as __attribute__((used)). Since
ts_shift is not referenced in inline assembly, we assume that we're simply
suppressing a warning here if the variable is declared but unreferenced.
