Subject: ide-generic: remove no longer needed ide_probe_legacy()
X-Git-Tag: v2.6.28-rc1~599^2~27
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=cf4049103be931fca133f66b3181490284a521c6;p=linux-2.6-omap-h63xx.git

ide-generic: remove no longer needed ide_probe_legacy()

There is now a generic solution [ide_generic_check_pci_legacy_iobases()]
so MIPS-specific ide_probe_legacy() is no longer necessary.
