[PATCH 10/16] MIPS: lantiq: falcon: sysctrl: fix request memory check logic

[Shiji Yang]

request_mem_region() will return NULL instead of error code
when the memory request fails. Therefore, we should check if
the return value is non-zero instead of less than zero. In
this way, this patch also fixes the build warnings:

you are breaking the whole idea of this interface, The functions are
exported for other kernel modules. By removing it you break them.

If we know that this interface is unsued, we should remove the
whole kernel module, but I don't know if it used somewhere.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]

Thank you for your review. It seems that MIPS/Lantiq platform still
rely on the vpe-mt module. I've sent another patch to fix these
vpe-mt compilation warnings. Suppress patches 12 and 13:

[PATCH 13/16] MIPS: vpe-mt: drop unused functions vpe_alloc() and vpe_start()

[Shiji Yang]

These two functions are defined but unused. Removing them to silence
the missing prototypes warnings:

I believe there's no actual dependency on the rest of the series?  In
general it is better not to mix patches for different subsystems in a
single series unless there's some interaction between them, it just
means people get more mail and makes it a bit less clear how things
should be applied.

Applied to

Thanks!

[16/16] spi: falcon: mark falcon_sflash_xfer() as static
        commit: 5fc2c383125c2b4b6037e02ad8796b776b25e6d0

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
