mmc: zynq_sdhci: fix uninitialized pointer deref on probe
Since commit 3d296365e4e8 ("mmc: sdhci: Add support for
sdhci-caps-mask") sdhci_setup_cfg() expects a valid sdhci_host mmc
field. Move the mmc field initialization before sdhci_setup_cfg()
call to avoid crash on mmc pointer dereference.
[this patch is based on commit 41a9fab8dac8 ("mmc: mv_sdhci: fix
uninitialized pointer deref on probe") by Baruch Siach]
