[PATCH] USB: EHCI full speed ISO bugfixes
This patch replaces the split ISO raw_mask calculation code in the iso_stream_init() function that computed incorrect numbers of high speed transactions for both input and output transfers. In the output case, it added a superfluous start-split transaction for all maxmimum packet sizes that are a multiple of 188. In the input case, it forgot to add complete-split transactions for all microframes covered by the full speed transaction, and the additional complete-split transaction needed for the case when full speed data starts arriving near the end of a microframe. These changes don't affect the lack of full speed bandwidth, but at least it removes the MMF errors that the HC raised with some input streams.
