From 945921db40d47cbac81becbf3c5c6f856cfb0d13 Mon Sep 17 00:00:00 2001 From: Pavel Skripkin Date: Fri, 17 Sep 2021 09:18:21 +0200 Subject: [PATCH] staging: r8188eu: remove the helpers of rtw_read16() Remove the unnecessary _rtw_read16() and usb_read16() and embed their code into the caller (i.e., rtw_read16()). _rtw_read16() is a mere redefinition of rtw_read16() and it is unneeded. usb_read16() was the only functions assigned to the (*_usb_read16) pointer, so we can simply remove it and make a direct call. This patch is in preparation for the _io_ops structure removal. Reviewed-by: Dan Carpenter Co-developed-by: Fabio M. De Francesco Signed-off-by: Fabio M.
