Subject: serial: 8250: Move ns16550a_goto_hispeed() to local header
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d81e50f6161ea169a14fbc17a94cd4943f5d8df6;p=linux-beck.git

serial: 8250: Move ns16550a_goto_hispeed() to local header

Prepare for 8250_core.c file split; move shared inline function
to local header file.
