[PATCH] serial: efm32: properly namespace location property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




While reviewing an i2c driver for efm32 that needs a similar property
Wolfram Sang pointed out that "location" is a too generic name for something
that is efm32 specific. So add an appropriate namespace and fall back to the
generic name in case of failure.
