X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b42057ab174d227d79eb426a9c66fb52cc2275ed;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ib_srpt: Convert to target_alloc_session usage

This patch converts ib_srpt internal assignments of
se_node_acl and transport_register_session() to use
the new alloc_session method.
