It seems this is your first attempt to patch something
in the linux kernel.

You should read https://kernelnewbies.org/ and you
should start with files in drivers/staging.

The leading "> " uses should not exist here.

You need your full legal name here.

This file probably does not need style changes as
it's pretty old and unlikely to change.

But if it did:

This needs separate lines for each single statement.

This is making the indentation worse as the parenthesized
sub-test block is now unaligned.

And some would prefer moving the && || to the end of the
previous line like:
