Subject: [PATCH] memstick: r592: Fix build warnings for !PM_SLEEP
Date: Thu, 2 Oct 2014 09:24:21 +0200 [thread overview]
Message-ID: <1412234661-21909-1-git-send-email-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
When PM_SLEEP is not enabled, the r592_clear_interrupts() function is
never used. If so, don't build it to prevent a compiler warning.
Signed-off-by: Thierry Reding <treding@nvidia.com>
