From 72e75de2df9a7116d0afbcd5810b2a8fd4bf7559 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Fri, 16 Sep 2005 18:49:22 +0200 Subject: [PATCH] [ALSA] remove redundent assignment to the ac97 device structure AC97 Codec Don't use dev.platform_data to store a reference to the containing ac97_t structure. Such assignment is redundent since we can deduce the ac97_t structure location from the contained device structure. This sets platform_data free for other purposes.
