remoteproc: imx_rproc: Fix NULL vs IS_ERR() bug in imx_rproc_addr_init()
The devm_ioremap_resource_wc() function never returns NULL, it returns error pointers. Update the error checking to match. Fixes: 67a7bc7f0358 ("remoteproc: Use of_reserved_mem_region_* functions for "memory-region"") Signed-off-by: Chen Ni <nichen@iscas.ac.cn> Reviewed-by: Peng Fan <peng.fan@nxp.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20260227091546.4044246-1-nichen@iscas.ac.cn Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org>
