From: Pavel Skripkin <redacted> Remove the unnecessary _rtw_read8() and usb_read8() and embed their code into the caller (i.e., rtw_read8()). _rtw_read8() is a mere redefinition of rtw_read8() and it is unneeded. usb_read8() was the only functions assigned to (*_usb_read8) pointer, so we can simply remove it and make a direct call. This patch is in preparation for the _io_ops structure removal. Co-developed-by: Fabio M. De Francesco <redacted> Signed-off-by: Fabio M.
