From db8cf334f66bdf1ba2b3d2f7128095fc9b7a6e2b Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Sun, 20 Dec 2009 20:15:19 +0100 Subject: [PATCH] ALSA: sbawe: fix memory detection Memory amount is increased before a successful write-read sequence is done. Thus, 512 kB of onboard memory is detected on memoryless cards like SB32. Move the increasing of memory counter after successful read is done.
