From 07368d32f1a67e797def08cf2ee3ea1647b204b6 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 9 Aug 2012 23:00:35 +0200 Subject: [PATCH] tpm_tis / PM: Fix unused function warning for CONFIG_PM_SLEEP According to a compiler warning, the tpm_tis_resume() function is not used for CONFIG_PM_SLEEP unset, so add a #ifdef to prevent it from being built in that case.
