From 68c85f2916222b15556ca44e2da0ee94f61f02da Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Thu, 10 Dec 2015 08:55:33 +0100 Subject: rtc: rv8803: fix handling return value of i2c_smbus_read_byte_data The function can return negative values, so its result should be assigned to signed variable. The problem has been detected using proposed semantic patch scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].
