Subject: [RESEND PATCH 1/2] thermal: imx_sc: add missing of_node_put for loop iteration
Date: Fri, 28 May 2021 07:50:35 -0400 [thread overview]
Message-ID: <20210528115036.18222-1-krzysztof.kozlowski@canonical.com> (raw)
Early exits from for_each_available_child_of_node() should decrement the
node reference counter. Reported by Coccinelle:
drivers/thermal/imx_sc_thermal.c:93:1-33: WARNING:
Function "for_each_available_child_of_node" should have of_node_put() before return around line 97.
