ACPI: Remove CONFIG_ACPI_PROCFS_POWER and cm_sbsc.c
There is no user of cm_sbs.c and CONFIG_ACPI_PROCFS_POWER. So remove them. Prepare for removing /proc/acpi Signed-off-by: Lan Tianyu <tianyu.lan@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

help

For backwards compatibility, this option allows
|
||||
deprecated power /proc/acpi/ directories to exist, even when
|
||||
they have been replaced by functions in /sys.
|
||||
The deprecated directories (and their replacements) include:
|
||||
/proc/acpi/battery/* (/sys/class/power_supply/*)
|
||||
/proc/acpi/ac_adapter/* (sys/class/power_supply/*)
|
||||
This option has no effect on /proc/acpi/ directories
|
||||
and functions, which do not yet exist in /sys
|
||||
This option, together with the proc directories, will be
|
||||
deleted in 2.6.39.
