Lindent isn't actually a very good source code reformatter
for Linux kernel code.

checkpatch can perform some of these transformations with
the --fix or --fix-inplace option.

Making changes for human readability of the source code
is generally good.

It's OK to start to read and familiarize yourself the the
kernel styles by using these tools, but better is to find
and fix actual defects in code instead of producing
whitespace changes that don't actually create any compiler
output differences.

Welcome in any case.
