linux-next: ahci_platform broken build

Hi,

Ah good catch, at some point I decided to prefix all the ahci_* functions defined in ahci_platform.c with ahci_platform_ instead of just ahci_. Somehow the functions got added with their new names directly in the "ahci-platform: Add support for devices with more then 1 clock" patch (this is intentional), but the calls added in that patch kept using the old names. Then in the "ahci-platform: Add enable_ / disable_resources helper functions" patch
the calls get moved to another place and now show up with the proper ahci_platform_* names. My bad.

Tejun it is probably easiest if you fix this up directly in your tree, let me know if you want a fixed up resend of the 2 patches in question instead.

Regards,

Hans

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

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.

It already happened and got resolved in the span of few patches. Shit happens. Let's just try to test each step better next time.

Thanks.
