Subject: ACPI: bus: add stub acpi_dev_found() to linux/acpi.h
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6eb17e0df74c036eba7548915b37f009403fe09e;p=openwrt%2Fstaging%2Fblogic.git

ACPI: bus: add stub acpi_dev_found() to linux/acpi.h

acpi_dev_found() will be used to detect if a given ACPI device is in the
system. It will be compiled in non-ACPI case, but the function is in
acpi_bus.h and acpi_bus.h can only be used in ACPI case, so this patch add
the stub function to linux/acpi.h to make compiled successfully in
non-ACPI cases.
