[PATCH] drivers/ide/ppc/pmac.c - CONFIG_BLK_DEV_IDEDMA_PMAC

[Magnus Damm <magnus.damm@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 389 bytes --]

Hello,

The file drivers/ide/ppc/pmac.c in vanilla 2.6.9 and 2.6.10-rc3 will
not compile with some configurations, the attached patch contains the
following fixes:

- Make sure pmac.c compiles with CONFIG_BLK_DEV_IDEDMA_PMAC unset.
- CONFIG_BLK_DEV_IDEDMA_PMAC needs CONFIG_BLK_DEV_IDEDMA_PCI.
- Removes the default value of CONFIG_BLK_DEV_IDEPCI due to recursive deps.

Thanks,

/ magnus
