usb: u132-hcd driver style clean up
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.
