Subject: target: Make target_core_subsystem defined as non static
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=56d128fa773c4ebfc1b806cb8143fb9d9647ba64;p=linux-beck.git

target: Make target_core_subsystem defined as non static

This patch makes the top-level target_core_subsystem array available
to other target code, which is required by EXTENDED_COPY to pin the
backend se_device using configfs_depend_item(), in order to ensure
it can't be removed for the duration of a EXTENDED_COPY operation.
