Subject: dmaengine: fsl_raid: add missing of_node_put() in fsl_re_probe()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=93e11eb1b745ee8dbd4f98f24b542d496c8f1e03;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dmaengine: fsl_raid: add missing of_node_put() in fsl_re_probe()

When terminating for_each_compatible_node() iteration with
break or return, of_node_put() should be used to prevent
stale device node references from being left behind.
