Subject: serial: Rename ns16550 functions to lower case
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=2d6bf754ced8fc66cb945d026b66865da4fede85;p=u-boot.git

serial: Rename ns16550 functions to lower case

Lower case should be used for function names. Update this driver and its
callers accordingly.
