Subject: [PATCH 2/3] ARM: omap1: avoid unused variable warning

The osk_mistral_init() contains code that is only compiled when
CONFIG_PM is set, but it uses a variable that is declared outside
of the #ifdef:

arch/arm/mach-omap1/board-osk.c: In function 'osk_mistral_init':
arch/arm/mach-omap1/board-osk.c:513:7: warning: unused variable 'ret' [-Wunused-variable]

This puts the variable in the same #ifdef to avoid the warning.
