Subject: [PATCH v2 3/9] arm: fix return value of parse_cpu_capacity
Date: Thu, 9 Feb 2017 09:25:19 +0000 [thread overview]
Message-ID: <20170209092525.6654-4-juri.lelli@arm.com> (raw)
In-Reply-To: <20170209092525.6654-1-juri.lelli@arm.com>
parse_cpu_capacity() has to return 0 on failure, but it currently returns
1 instead if raw_capacity kcalloc failed.
Fix it by removing the negation of the return value.
