[alsa-devel] [PATCH 001/002] ASoC: Replace max98090 Device Driver
Jerry Wong
Jerry.Wong at maximintegrated.com
Tue Feb 5 06:48:47 CET 2013
From: Jerry Wong <jerry.wong at maximintegrated.com>
This patch removes the existing max98090 driver prior to installing a more
complete one.
---
The original author is okay to replace
his recently submitted driver with this one.
"... Would you mind if we began this now by replacing the existing
driver with the one attached? ..." - Jerry
"... But of course I agree to replace it to your code. Please send it to
upstream... " - Morimoto-san
