Subject: [PATCH -next] soc: ti: pruss: Fix return value check
Date:   Tue, 15 Sep 2020 07:57:32 +0000
Message-ID: <20200915075732.100804-1-weiyongjun1@huawei.com>
MIME-Version: 1.0
Content-Type:   text/plain; charset=US-ASCII
Content-Transfer-Encoding: 7BIT
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In case of error, the function of_device_get_match_data() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

Fixes: ba59c9b43c86 ("soc: ti: pruss: support CORECLK_MUX and IEPCLK_MUX")
