From d34e4e00adbbc91ff9fc96ed9a4e4b65161868da Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 9 Aug 2012 15:47:15 +0200 Subject: ALSA: platform: Check CONFIG_PM_SLEEP instead of CONFIG_PM When CONFIG_PM is set but CONFIG_PM_SLEEP is unset, SIMPLE_DEV_PM_OPS() ignores the given functions, and this leads to compile warnings. For avoiding this, simply check CONFIG_PM_SLEEP instead of CONFIG_PM.

It is dropped and the previous and subsequent tests are combined. In the second case, add an initialization of retval on failure of ioremap.
