From mboxrd@z Thu Jan 1 00:00:00 1970 From: weiyongjun1@huawei.com (Wei Yongjun) Date: Thu, 28 Dec 2017 02:40:49 +0000 Subject: [PATCH -next] clk: meson-axg: fix return value check in axg_clkc_probe() Message-ID: <1514428849-61681-1-git-send-email-weiyongjun1@huawei.com> To: linus-amlogic@lists.infradead.org List-Id: linus-amlogic.lists.infradead.org In case of error, the function devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
