From d41378713eef6a7d9d9c30cb9a6181ad72f69596 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 13 Nov 2019 21:31:58 +0300 Subject: net: atlantic: Signedness bug in aq_vec_isr_legacy() irqreturn_t type is an enum and in this context it's unsigned, so "err" can't be irqreturn_t or it breaks the error handling. In fact the "err" variable is only used to store integers (never irqreturn_t) so it should be declared as int. I removed the initialization because it's not required. Using a bogus initializer turns off GCC's uninitialized variable warnings. Secondly, there is a GCC warning about unused assignments and we would like to enable that feature eventually so we have been trying to remove these unnecessary initializers.
