From a115d24a636e892ddd1ae58f8e23c78a0390cb68 Mon Sep 17 00:00:00 2001 From: wengjianfeng Date: Mon, 12 Apr 2021 10:20:06 +0800 Subject: nfc: pn533: remove redundant assignment In many places,first assign a value to a variable and then return the variable. which is redundant, we should directly return the value. in pn533_rf_field funciton,return rc also in the if statement, so we use return 0 to replace the last return rc.
