[patch 13/30] PS3: System-bus modinfo attribute
From: Geoff Levand <hidden>
Date: 2007-06-12 18:55:38
From: David Woodhouse <dwmw2@infradead.org> Add modinfo attribute to ps3_system_bus devices. Also make them all children of the same ps3_system_bus 'device' so they appear in a corresponding subdirectory under /sys/devices Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Geoff Levand <redacted> --- arch/powerpc/platforms/ps3/system-bus.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+)
