Subject: powerpc/fadump: Fix build break when CONFIG_PROC_VMCORE=n
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2685f826e5ffd1ab73b26fd5ac4e1f7048cb6ff6;p=linux-beck.git

powerpc/fadump: Fix build break when CONFIG_PROC_VMCORE=n

The fadump code calls vmcore_cleanup() which only exists if
CONFIG_PROC_VMCORE=y. We don't want to depend on CONFIG_PROC_VMCORE,
because it's user selectable, so just wrap the call in an #ifdef.
