Subject: serial: make serial_stub_* to static functions
X-Git-Tag: v2017.07~37
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=49ddcf3e0e923040ef554d9ea033e0d8ba7e80e1;p=u-boot

serial: make serial_stub_* to static functions

Add missing static to serial_stub_puts().

Unexport serial_stub_{getc,tstc} because they are used locally.
