This certainly works for my particular use case, however, Sergei
Shtylyov, who wrote the da8xx musb glue layer originally, seemed to
recall in his review of the patch series that this really is necessary
for OTG mode to work properly.
By the way, there is v3 of this patch series already, although this
patch is nearly the same.
