I was converting a semaphore in this file to a mutex when I noticed that
this file has some fairly rampant style problems. Practically every line
has spaces instead of tabs .. Once I cleared that up, checkpatch.pl showed
a number of other problem.. I think this file might be a good one to review
for new style checks that could be added..

Below are the only two remaining which I didn't remove. 

#5083: FILE: drivers/usb/host/u132-hcd.c:2907:
+               error:

WARNING: labels should not be indented
#5087: FILE: drivers/usb/host/u132-hcd.c:2911:
+               stall:

These labels are actually inside a switch statement, and they are right
under "default:". "default:" appears to be exempt and these other label
should be too, or default shouldn't be exempt.

I also deleted a few lines due to single statements inside { } , 

if (is_error()) {
	return;
}

becomes,

if (is_error())
	return;

with one line deleted.

the following patch uses 16 write urbs and a writsize of wMaxPacketSize

I have got a cypress usb-ide bridge and I would like to tune or monitor
my disk with tools like hdparm, hddtemp or smartctl.

My controller support a way to send raw ATA command to the disk with
something call atacb (see
http://download.cypress.com.edgesuite.net/design_resources/datasheets/contents/cy7c68300c_8.pdf).

Atacb support can be added for each application, but there is some disadvantages :
- all application need to be patched
- A race is possible if there other accesses, because the emulation can
be split in 2 atacb scsi transactions. One for sending the command, one
for reading the register (if ck_cond is set). 

I have implemented the emulation in usb-storage with a special proto_handler,
and an unsual entry.

Some EHCI fault paths with large control transfers aren't coded.  Avoid
problems by rejecting transfers that may need two qTDs (16+ KB).  This is
mostly paranoia; even 4 KB transfers are rare, and most HCDs use lower
limits (so it's unlikely anyone would ever try such a thing).
