X-Git-Tag: v2.6.17-rc1~1182^2~37
X-Git-Url: http://git.samba.org/samba.git/?p=sfrench%2Fcifs-2.6.git;a=commitdiff_plain;h=4b2f3ededc035525038a7a9247074243dac6b351

[PATCH] libata: fold ata_dev_config() into ata_dev_configure()

ata_dev_config() needs to be done everytime a device is configured.
Fold it into ata_dev_configure().
