PATCH 2/5 staging: r8188eu: convert switch to if statement in mgt_dispatcher()

In reply to Michael Straube

The 'switch (GetFrameSubType(pframe))' in mgt_dispatcher() has only one case that does something different than the default case. Convert the switch to an if statement to improve readability.

PATCH 4/5 staging: r8188eu: rtw_os_recv_resource_init() does nothing

In reply to Michael Straube

The function rtw_os_recv_resource_init() just returns _SUCCESS and the return value is not checked by the caller. Remove the function.
