Re: [PATCH] libata: fix broken Kconfig setup

[Jeff Garzik]

Here's a patch for the quirk.  I'll split this off from the sata-menu 
discussion.  Jesse, I presume this also fixes the problem for you?


This change makes quirk_intel_ide_combined() dependent on the precise 
conditions under which it is needed:
* IDE is built in
* IDE SATA option is not set
* ata_piix or ahci drivers are enabled

This fixes an issue where some modular configurations would not cause 
the quirk to be enabled.
