From 7d73f539b514e3404c8d4210aa44aa92c0d67b43 Mon Sep 17 00:00:00 2001 From: Trent Piepho Date: Mon, 13 Aug 2007 08:21:57 -0700 Subject: cx88: Make card database more memory efficient From: Trent Piepho The vmux setting is only two bits, but was taking up a whole 32 in the input description struct. By changing it to a two-bit bitfield, it can fit in what was padding space before and drop the input size by 4 bytes, from 28 to 24. This drops the board description struct, which has 9 inputs, from 280 to 244 bytes. Total driver size decreases by 2108 bytes.
