This cleans up the most ugly workaround in this driver. There are no functional changes yet in the decoding algorithm, but we improve the following things: * Get rid of spurious warning messages on systems with fast HRTIMER. * If the clock is not fast enough for decoding to work, we give up immediately. * In that case we return EAGAIN instead of EIO, so it's easier to discriminate causes of failure. Returning EAGAIN is somewhat controversial: It's technically correct as a faster clock might become available. OTOH once all clocks are enabled this is a permanent error. There is no ECLOCKTOOSLOW error code. Signed-off-by: Harald Geyer <harald@ccbib.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org> |
