Zhang Changzhong 0bc1c2d4a7 slimbus: qcom: fix potential NULL dereference in qcom_slim_prg_slew() ... [ Upstream commit 428bb001143cf5bfb65aa4ae90d4ebc95f82d007 ] platform_get_resource_byname() may fail and in this case a NULL dereference will occur. Fix it to use devm_platform_ioremap_resource_byname() instead of calling platform_get_resource_byname() and devm_ioremap(). This is detected by Coccinelle semantic patch. @@ expression pdev, res, n, t, e, e1, e2; @@ res = \(platform_get_resource\|platform_get_resource_byname\)(pdev, t, n); + if (!res) + return -EINVAL; ... when != res == NULL e = devm_ioremap(e1, res->start, e2); Fixes: ad7fcbc308 ("slimbus: qcom: Add Qualcomm Slimbus controller driver") Signed-off-by: Zhang Changzhong <zhangchangzhong@huawei.com> Link: https://lore.kernel.org/r/1607392473-20610-1-git-send-email-zhangchangzhong@huawei.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-12-30 11:53:47 +01:00
