[PATCH] regulator: fan53555: Use of_device_get_match_data() to simplify probe

[Jisheng Zhang]

if fan53555_regulator_probe() is called and the "client->dev.of_node"
isn't NULL, it means OF registered a device with a valid compatible
string, so match cannot be NULL.

Use of_device_get_match_data() to retrieve the drvdata pointer.  No
functional change intended.

Applied "regulator: fan53555: Use of_device_get_match_data() to simplify probe" to the regulator tree

[Mark Brown]

The patch

   regulator: fan53555: Use of_device_get_match_data() to simplify probe

has been applied to the regulator tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git 

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.
