Currently platform specific private data initialisation is done by dw_mci_exynos_priv_init and dw_mci_exynos_parse_dt.As we already have separate platform specific device tree parser dw_mci_exynos_parse_dt, move the dw_mci_exynos_priv_init code to dw_mci_exynos_parse_dt. We can use the dw_mci_exynos_priv_init to do some actual platform specific initialisation of SMU and etc. Signed-off-by: Yuvaraj Kumar C D <yuvaraj.cd@samsung.com> --- drivers/mmc/host/dw_mmc-exynos.c | 31 +++++++++++++++---------------- 1 file changed, 15 insertions(+), 16 deletions(-)
