[PATCH 26/50] debug_ll ns16550: Do not define PUTC_LL()

Sascha Hauer s.hauer at pengutronix.de
Fri Mar 3 01:21:07 PST 2023


The ns16550 debug_ll helper always defines PUTC_LL() when included.
This is not always desired, so rename it to debug_ll_ns16550_putc()
and let the user define PUTC_LL() when desired.
