From dedc6a7803d9c9795b504ffd8530a4ba7b3fd9ed Mon Sep 17 00:00:00 2001 From: Jim Cromie Date: Mon, 9 Jan 2006 23:24:41 +0100 Subject: [PATCH] hwmon: Use attribute arrays in pc87360 Convert individual sensors to sensor-attr arrays by each sensor type, and initialize them in loops instead of long blocks of individual calls.

This shrinks the compiled module from 12.0 kB to 9.6 kB. We certainly should do the same for as many hardware monitoring drivers as possible. This, together with a nice chip design by Fintek, makes this driver very small, both in terms of number of lines of code and memory consumption.
