[ Upstream commit ac004e84164e27d69017731a97b11402a69d854b ]
During initialization the driver issues a reset to the device and waits for 100ms before checking if the firmware is ready. The waiting is necessary because before that the device is irresponsive and the first read can result in a completion timeout.
While 100ms is sufficient for Spectrum-1 and Spectrum-2, it is insufficient for Spectrum-3.
Fix this by increasing the timeout to 200ms.
