From 5df9de5a40b00c965febad655773d6fb9a7961d5 Mon Sep 17 00:00:00 2001 From: Ivan Safonov Date: Sat, 1 Aug 2020 21:02:35 +0300 Subject: [PATCH] staging: r8188eu: replace rtw_netdev_priv define with inline function The function guarantees type checking of arguments and return value. Result of rtw_netdev_priv macro can be assigned to pointer with incompatible type without warning. The function allow compiler to perform this check.
