Fixes most of checkpatch warnings and errors in USB gadget stack.
The most frequently encountered problems are:
1) "(foo*)", "foo * bar", "foo* bar"
2) C99 // comments
3) No spaces before/after/around '?', ':', '=', '==', ',', '&', '('
4) Spaces before '['
5) Spaces between function names and '('
6) Block braces in wrong places
7) Spaces before tabs
8) Macros with complex values not enclosed in parenthesis
9) Multiline comments start just after /*

* USB device controllers have lots of quirks. Use these macros in

|
* gadget drivers or other code that needs to deal with them, and which
|
|
* autoconfigures instead of using early binding to the hardware.
|
|
*
|
|
* This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
|
|
* some config file that gets updated as new hardware is supported.
|
|
* (And avoiding all runtime comparisons in typical one-choice configs!)
|
|
*
|
|
* NOTE: some of these controller drivers may not be available yet.
|
|
* Some are available on 2.4 kernels; several are available, but not
|
|
* yet pushed in the 2.6 mainline tree.
