From fb239c1209bb0f0b4830cc72507cc2f2d63fadbd Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Thu, 8 Feb 2018 16:57:12 -0800 Subject: rtlwifi: rtl8192cu: Remove variable self-assignment in rf.c In _rtl92c_get_txpower_writeval_by_regulatory() the variable writeVal is assigned to itself in an if ... else statement, apparently only to document that the branch condition is handled and that a previously read value should be returned unmodified. The self-assignment causes clang to raise the following warning: drivers/net/wireless/realtek/rtlwifi/rtl8192cu/rf.c:304:13: error: explicitly assigning value of variable of type 'u32' (aka 'unsigned int') to itself [-Werror,-Wself-assign] writeVal = writeVal; Delete the branch with the self-assignment.
