Subject: fsl_sata: Fix compile error when CONFIG_LBA48 is not defined
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=007a28d54de7ff5794b14854f12cda6e49ec1122;p=u-boot.git

fsl_sata: Fix compile error when CONFIG_LBA48 is not defined

If CONFIG_LBA48 is not defined, the element lba48 of struct sata_dev_desc
is not avaible, and can't be used.
