Subject: Applied "regulator: bd718x7: Remove double indirection for bd718xx_pmic_inits.rdatas" to the regulator tree

The patch

   regulator: bd718x7: Remove double indirection for bd718xx_pmic_inits.rdatas

has been applied to the regulator tree at

   https://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.  

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.

Thanks,
Mark

Subject: [PATCH] regulator: bd718x7: Remove double indirection for
 bd718xx_pmic_inits.rdatas
MIME-Version: 1.0

With gcc 4.1:

    drivers/regulator/bd718x7-regulator.c: In function ‘bd718xx_probe’:
    drivers/regulator/bd718x7-regulator.c:1020: warning: initialization from incompatible pointer type
    drivers/regulator/bd718x7-regulator.c:1024: warning: initialization from incompatible pointer type

Apparently this old compiler can't handle the obscure double
indirection.

However, there is no need for a double indirection.  Just store a
pointer to the array instead, like other drivers tend to do.
