linux-next: ahci_platform broken build

[Tim Gardner <tim.gardner@canonical.com>]

Gents  - while reviewing some patches for arm64 in Ubuntu I noticed that 
there is at least one patch sequence in linux-next that breaks the build.

156c5887948cd191417f18026aab9ce26e5a95da ahci-platform: Add support for 
devices with more then 1 clock
039ece38da45f5e6a94be3aa7611cf3634bc2461 libahci: Allow drivers to 
override start_engine

For example:

git reset --hard 156c5887948cd191417f18026aab9ce26e5a95da
echo "CONFIG_SATA_AHCI_PLATFORM=y" >> .config
make oldconfig scripts prepare
make M=drivers/ata

cc1: some warnings being treated as errors
make[1]: *** [drivers/ata/ahci_platform.o] Error 1

The compile problem is then fixed in 
96a01ba52c60fdd74dd6e8cf06645d06515b1396 (ahci-platform: Add enable_ / 
disable_resources helper functions) which is not really kosher.

It seems like you ought to fix this before the 3.15 merge window opens.
