staging: ks7010: add hostif_generic_request()
Driver contains duplicate code. Host interface has numerous request functions which allocate memory for a request header. Each request header is different but all contain, as the first member, a hostif_hdr structure. This structure has size and event members which need to be set. By defining a helper function to allocate the memory and set the initial hostif_hdr members code duplication is reduced. Add function to allocate memory for a host interface request. Set 'size' and 'event' members. Remove duplicate code using newly defined function. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
