Fixes the following warnings,
arch/arm/mach-msm/board-trout.c: In function 'trout_init':
arch/arm/mach-msm/board-trout.c:71: error: 'system_rev' undeclared (first use in this function)
arch/arm/mach-msm/board-trout.c:71: error: (Each undeclared identifier is reported only once
arch/arm/mach-msm/board-trout.c:71: error: for each function it appears in.)
and
arch/arm/mach-msm/board-trout-panel.c: In function 'trout_init_panel':
arch/arm/mach-msm/board-trout-panel.c:267: error: 'system_rev' undeclared (first use in this function)
arch/arm/mach-msm/board-trout-panel.c:267: error: (Each undeclared identifier is reported only once
arch/arm/mach-msm/board-trout-panel.c:267: error: for each function it appears in.)
This came in with the following commit 9f97da78bf
which removes asm/system.h
