If anyone has any objections, please let me know. ------------------ [ Upstream commit 4f32fb921b153ae9ea280e02a3e91509fffc03d3 ] rdmavt uses a crazy system that looses the type checking when assinging functions to struct ib_device function pointers. Because of this the signature to this function was not changed when the below commit revised things. Fix the signature so we are not calling a function pointer with a mismatched signature.
