SubjectApplied "regulator: stm32-pwr: Fix return value check in stm32_pwr_regulator_probe()" to the regulator tree
The patch

regulator: stm32-pwr: Fix return value check in stm32_pwr_regulator_probe()

has been applied to the regulator tree at for-5.2

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Subject: [PATCH] regulator: stm32-pwr: Fix return value check in

In case of error, the function of_iomap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

Fixes: 6cdae8173f67 ("regulator: Add support for stm32 power regulators")
