[PATCH] USB: isp116x-hcd: cleanup
The attached patch makes a cleanup of isp116x-hcd. Most of the volume of
the patch comes from 2 sources: moving the code around to get rid of a
few function prototypes and reworking register dumping functions/macros.
Among other things, switched over from using procfs to debugfs.
Cleanup. The following changes were made:
- Rework register dumping code so it can be used for dumping
to both syslog and debugfs.
- Switch from procfs to debugfs..
- Die gracefully on Unrecoverable Error interrupt.
- Fix memory leak in isp116x_urb_enqueue(), if HC happens to
die in a narrow time window.
- Fix a 'sparce' warning (unnecessary cast).
- Report Devices Removable for root hub ports by default
(was Devices Permanently Attached).
- Move bus suspend/resume functions down in code to get rid of
a few function prototypes.
- A number of one-line cleanups.
- Add an entry to MAINTAINERS.
