Subject: [PATCH v4 10/18] staging: r8188eu: remove the helpers of rtw_write_port()
From: Pavel Skripkin <paskripkin@...il.com>
Remove the unnecessary _rtw_write_port() and usb_write_port() and embed
their code into the caller (i.e., rtw_write_port()).
_rtw_write_port() is a mere redefinition of rtw_write_port() and it is
unneeded. usb_write_port() was the only functions assigned to the
(*_usb_write_port) pointer, so we can simply remove it and make a direct
call.
This patch is in preparation for the _io_ops structure removal.
