Subject: mmc: sdhci: zynq: Define private structure arasan_sdhci_priv
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=51b88bd1cbba67da399469be55a2b4b855d3c8af;p=thirdparty%2Fu-boot.git

mmc: sdhci: zynq: Define private structure arasan_sdhci_priv

Deine private structure arasan_sdhci_priv instead of sdhci_host
as private. This allows us in adding more private data  as required
for usage in driver.
