Subject: [PATCH] sunxi-mmc: fixup: revert "add host initialization for when
|
|
the sdio irq is enabled"
|
|
|
|
This is not necessary since when the host is not initialized at this point
|
|
yet the irq line from the mmc controller is not enabled, so writing the
|
|
host controller interrupt mask cannot cause interrupts at this point.
|
|
|
|
More over doing this is wrong, as it leads to unbalanced calling of
|
|
clk_prepare_enable and regulator_power_on.
