[PATCH 1/3] staging: r8188eu: remove _io_ops structure

Fabio M. De Francesco
2021-09-04T15:04:59Z

From: Pavel Skripkin <paskripkin@gmail.com>

io_ops abstraction is useless in this driver, since there is only one ops
registration. Without io_ops we can get rid of indirect calls mess and
shorten the calls chain.
