[PATCH v4 11/18] staging: r8188eu: remove the helpers of usb_read_port_cancel()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Pavel Skripkin <paskripkin@xxxxxxxxx>

Remove the unnecessary _rtw_read_port_cancel() and usb_read_port_cancel()
and embed their code into the caller (i.e., rtw_read_port_cancel()).

_rtw_read_port_cancel() is a mere redefinition of rtw_read_port_cancel()
and it is unneeded. usb_read_port_cancel() was the only functions assigned
to the (*_usb_read_port_cancel) pointer, so we can simply remove it and
make a direct call.

This patch is in preparation for the _io_ops structure removal.
