Long identifier names like "current_network.beacon_interval",
which is 31 chars long, make the 80 column limit somewhat silly.

It's OK to ignore checkpatch warnings when changing the code
is less readable.

Most all of these are less nice than the original.

For instance, if this were to be changed (and it doesn't
need to be) perhaps:

		mod_timer(&ieee->beacon_timer,
			  jiffies +
			  msecs_to_jiffies(ieee->current_network.beacon_interval - 5));

which is still > 80 columns, but it removes an unnecessary
set of parentheses.

Breaking the msecs_to_jiffies() at the function name is
otherwise rather unsightly.

Always strive for readability and clarity over serving
some mindless script.
