[PATCH v6 06/19] staging: r8188eu: remove the helpers of usb_write16()

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

 



From: Pavel Skripkin <paskripkin@xxxxxxxxx>

Remove the unnecessary _rtw_write16() and usb_write16() and embed their
code into the caller (i.e., rtw_write16()).

_rtw_write16() is a mere redefinition of rtw_write16() and it is unneeded.
usb_write16() was the only functions assigned to the (*_usb_write16)
pointer, so we can simply remove it and make a direct call.

This patch is in preparation for the _io_ops structure removal.
