+Subject: mmc: core: fix return value check in devm_mmc_alloc_host()
+
+From: Yang Yingliang <yangyingliang@huawei.com>
+
+commit 71d04535e853305a76853b28a01512a62006351d upstream.
+
+mmc_alloc_host() returns NULL pointer not PTR_ERR(), if it
+fails, so replace the IS_ERR() check with NULL pointer check.
+
+In commit 418f7c2de133 ("mmc: meson-gx: use devm_mmc_alloc_host"),
+it checks NULL pointer not PTR_ERR, if devm_mmc_alloc_host() fails,
+so make it to return NULL pointer to keep same with mmc_alloc_host(),
+the drivers don't need to change the error handle when switch to
+use devm_mmc_alloc_host().
+
+Fixes: 80df83c2c57e ("mmc: core: add devm_mmc_alloc_host")
