sparse was giving the following warning:
warning: context imbalance in 's3c_hsotg_ep_enable'
- different lock contexts for basic block
we were returning ENOMEM while still holding the spinlock.
The sparse warning was fixed by releasing the spinlock before return.
This patch depends on the previous patch of the series.
