When Jiri suggested to use a define, I did not read it as meaning a
define local within the driver, but rather a define that would span
beyond you driver that would match what is expected to be used by
drivers/i2c/busses/i2c-designware-pcidrv.c.
As a matter of fact, there are quite a few drivers that expect to use
this driver name:
git grep i2c_designware *
drivers/i2c/busses/i2c-designware-pcidrv.c:MODULE_ALIAS("i2c_designware-pci");
drivers/i2c/busses/i2c-designware-platdrv.c:MODULE_ALIAS("platform:i2c_designware");
drivers/i2c/busses/i2c-designware-platdrv.c: .name =
"i2c_designware",
drivers/mfd/intel-lpss.c: .name = "i2c_designware",
drivers/mfd/intel_quark_i2c_gpio.c:#define
INTEL_QUARK_I2C_CONTROLLER_CLK "i2c_designware.0"
drivers/mfd/intel_quark_i2c_gpio.c: .name = "i2c_designware",
drivers/net/ethernet/wangxun/txgbe/txgbe_phy.c: snprintf(clk_name,
sizeof(clk_name), "i2c_designware.%d",
drivers/net/ethernet/wangxun/txgbe/txgbe_phy.c: info.name =
"i2c_designware";
so they should all be covered by using a define under
include/linux/i2c-designware.h.
