net/atm/lec.c: checkpatch cleanups
Convert #include <asm... to #include <linux...
Mostly 80 column wrapped.
Spacing cleanups
Convert printks to pr_<level>
Use print_hex_dump
Move embedded assigns out of tests
Move trailing statements to new lines
Remove unnecessary braces around single line statements
switch/case cleanups
Removed paren around returns
Use %pM
Moved leading continuation logical tests to end of previous line
