Modify the fixed regulator driver to extract fixed_voltage_config from device tree when passed, instead of getting it through platform_data structures (on non-DT builds) Signed-off-by: Rajendra Nayak <redacted> --- drivers/regulator/fixed.c | 18 +++++++++++++++++- 1 files changed, 17 insertions(+), 1 deletions(-)diff --git a/drivers/regulator/fixed.c b/drivers/regulator/fixed.c index c09f791..0a9a10d 100644 --- a/drivers/regulator/fixed.c +++ b/drivers/regulator/fixed.c@@ -140,10 +140,15 @@ static struct regulator_ops fixed_voltage_ops = { static int __devinit reg_fixed_voltage_probe(struct platform_device *pdev) { - struct fixed_voltage_config *config = pdev->dev.platform_data; + struct fixed_voltage_config *config;
This line doesn't actually need to change; just override it below if the of_node is present.
