This array identifies the regulator's\nconsumers by dev_name and supply(-name). Which requires a constant\ndev_name.\n\nThis commit adds a dev_name field to i2c_board_info allowing\nplatform code to set a contstant dev_name so that the device can\nbe identified by its dev_name in other platform code.\n\nSigned-off-by: Hans de Goede <hdegoede@redhat.com>\n---\n drivers/i2c/i2c-core-base.c | 10 ++++++++--\n include/linux/i2c.h | 2 ++\n 2 files changed, 10 insertions(+), 2 deletions(-)", "diff": "diff --git a/drivers/i2c/i2c-core-base.c b/drivers/i2c/i2c-core-base.c\nindex 45fafcc88b93..5cdf3b947c23 100644\n--- a/drivers/i2c/i2c-core-base.c\n+++ b/drivers/i2c/i2c-core-base.c\n@@ -672,10 +672,16 @@ static void i2c_adapter_unlock_bus(struct i2c_adapter *adapter,\n }\n \n static void i2c_dev_set_name(struct i2c_adapter *adap,\n-\t\t\t struct i2c_client *client)\n+\t\t\t struct i2c_client *client,\n+\t\t\t struct i2c_board_info const *info)\n {\n \tstruct acpi_device *adev = ACPI_COMPANION(&client->dev);\n \n+\tif (info && info->dev_name) {\n+\t\tdev_set_name(&client->dev, \"i2c-%s\", info->dev_name);\n+\t\treturn;\n+\t}\n+\n \tif (adev) {\n \t\tdev_set_name(&client->dev, \"i2c-%s\", acpi_dev_name(adev));\n \t\treturn;\n@@ -772,7 +778,7 @@ i2c_new_device(struct i2c_adapter *adap, struct i2c_board_info const *info)\n \tclient->dev.of_node = info->of_node;\n \tclient->dev.fwnode = info->fwnode;\n \n-\ti2c_dev_set_name(adap, client);\n+\ti2c_dev_set_name(adap, client, info);\n \n \tif (info->properties) {\n \t\tstatus = device_add_properties(&client->dev, info->properties);\ndiff --git a/include/linux/i2c.h b/include/linux/i2c.h\nindex 701ad26fa6b4..d3655cfe9a3e 100644\n--- a/include/linux/i2c.h\n+++ b/include/linux/i2c.h\n@@ -310,6 +310,7 @@ static inline bool i2c_detect_slave_mode(struct device *dev) { return false; }\n * @type: chip type, to initialize i2c_client.name\n * @flags: to initialize i2c_client.flags\n * @addr: stored in i2c_client.addr\n+ * @dev_name: Overrides the default <busnr>-<addr> dev_name if set\n * @platform_data: stored in i2c_client.dev.platform_data\n * @archdata: copied into i2c_client.dev.archdata\n * @of_node: pointer to OpenFirmware device node\n@@ -334,6 +335,7 @@ struct i2c_board_info {\n \tchar\t\ttype[I2C_NAME_SIZE];\n \tunsigned short\tflags;\n \tunsigned short\taddr;\n+\tconst char\t*dev_name;\n \tvoid\t\t*platform_data;\n \tstruct dev_archdata\t*archdata;\n \tstruct device_node *of_node;\n", "prefixes": [ "v3", "01/11" ] }
