Subject: rbd: drop rbd_obj_method_sync() version parameter
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e2a58ee55b0f132c2a6cbf2504a1c651b261fb67;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

rbd: drop rbd_obj_method_sync() version parameter

Only NULL is passed as the version argument to rbd_obj_method_sync(),
so get rid of it.
