From ce0b80a71ba1a749abaffa5e5883582d54ffe66e Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 24 Oct 2013 16:06:32 +0200 Subject: [PATCH] thinkpad_acpi: Fix build error when CONFIG_SND_MAX_CARDS > 32 commit cab6661344f14a09d7aecdf821a40f68ef9b18cc upstream. SNDRV_CARDS can be specified via Kconfig since 3.11 kernel, so this can be over 32bit integer range, which leads to a build error.
