Subject: [PATCH] ARM: socfpga: PM: Add missing put_device() call in socfpga_setup_ocram_self_refresh()
Date: Sat, 9 Nov 2019 19:01:19 +0100 [thread overview]
Message-ID: <c45a8e00-3fc9-adba-1a46-5f2c4149953e@web.de> (raw)
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 9 Nov 2019 18:48:44 +0100
A coccicheck run provided information like the following.
arch/arm/mach-socfpga/pm.c:87:1-7: ERROR: missing put_device;
call of_find_device_by_node on line 41, but without a corresponding
object release within this function.
Generated by: scripts/coccinelle/free/put_device.cocci
Thus add the missed function call to fix the resource management for
this function implementation.
Fixes: 44fd8c7d4005f660f48679439f0a54225ba234a4 ("ARM: socfpga: support suspend to ram")
