From 1b403c6dd7790b631a983d504eeb1b8c698d0470 Mon Sep 17 00:00:00 2001 From: Pavel Skripkin Date: Fri, 17 Sep 2021 09:18:26 +0200 Subject: [PATCH] staging: r8188eu: remove the helpers of usb_writeN() Remove the unnecessary _rtw_writeN() and usb_writeN() and embed their code into the caller (i.e., rtw_writeN()). _rtw_writeN() is a mere redefinition of rtw_writeN() and it is unneeded. usb_writeN() was the only functions assigned to the (*_usb_writeN) 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.
