Subject: of/platform: Make of_platform_device_destroy globally visible
X-Git-Tag: MMI-PSA29.97-13-9~5541^2~2
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c2372c20425bd75a5527b3e2204059762190f6ca;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

of/platform: Make of_platform_device_destroy globally visible

of_platform_device_destroy is the counterpart to
of_platform_device_create which is a non-static function.

After creating a platform device it might be neccessary
to destroy it to deal with -EPROBE_DEFER where a
repeated of_platform_device_create call would fail otherwise.

Therefore also make of_platform_device_destroy globally visible.
