[PATCH 5.10 251/509] mfd: stmfx: Fix error path in stmfx_chip_init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Amelie Delaunay <amelie.delaunay@xxxxxxxxxxx>

[ Upstream commit f592cf624531286f8b52e40dcfc157a5a7fb115c ]

In error path, disable vdd regulator if it exists, but don't overload ret.
Because if regulator_disable() is successful, stmfx_chip_init will exit
successfully while chip init failed.
