There is no error handle when ocfs2_journal_access_di() is failed.
And also it doesn't need to call ocfs2_dx_dir_insert() when
ocfs2_journal_access_db() is failed.

The current code always sent packets without data on the primary channel.
Properly distribute sending of packets with no data amongst all available
channels. I would like to thank Long Li for noticing this problem.

Size the queue depth based on the ringbuffer size. Also accomodate for the
fact that we could have multiple channels (ringbuffers) per adaptor.

Increase the default ring buffer size as this can significantly
improve performance especially on high latency storage back-ends.

While testing on some high latency storage backends, to get the advertised IOPS,
we have to increase the size of the ringbuffer. Address this issue.

A recent bug fix I did that was marked for stable backports
introduced a slightly wrong dependency on CONFIG_OMAP_CONTROL_PHY.
I was missing the fact that the PHY driver already stubs out the
omap_control_usb_set_mode, and we only need to add a dependency
to prevent the musb-omap2430 driver from
