Subject: [PATCH] thermal: thermal_of: fix error return code of thermal_of_populate_bind_params()
Date: Sat,  6 Mar 2021 06:11:06 -0800	[thread overview]
Message-ID: <20210306141106.18695-1-baijiaju1990@gmail.com> (raw)

When kcalloc() fails and __tcbp is NULL, no error return code of
thermal_of_populate_bind_params() is assigned.
To fix this bug, ret is assigned with -ENOMEM in this case.
