Subject: regulator: AXP20x: fix wrong call to of_find_node_by_name
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a6016c523ef2f86d4ec60b87b480dd1a2c5ae33a;p=linux-beck.git

regulator: AXP20x: fix wrong call to of_find_node_by_name

The of_find_node_by_name function will search for a DT node named
"regulators" after the provided np node, but will not ensure that this node
is a child of np.
This might result in retrieving a "regulators" node that is not related to
the axp20x PMIC.
