From 189d34e747e9540b70227f6682bd680868d90b10 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Thu, 6 Nov 2008 16:49:55 -0500 Subject: ALSA: cs5535audio: check OLPC's Analog Input status vis GPIO Checking the HPF register is irrelevant; HPF is secondary to the AI mode. Instead, check for Analog Input mode via GPIO.
