Subject[PATCH] nvmem: meson-mx-efuse: fix ptr_ret.cocci warnings
From: Fengguang Wu <fengguang.wu@intel.com>

drivers/nvmem/meson-mx-efuse.c:237:1-3: WARNING: PTR_ERR_OR_ZERO can be used


Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR

Generated by: scripts/coccinelle/api/ptr_ret.cocci

Fixes: 37ef5352c0f7 ("nvmem: meson-mx-efuse: Convert to use devm_nvmem_register()")
