From b586a95e26067973a582b82c55a9fabc8f6f03e0 Mon Sep 17 00:00:00 2001 From: Shubhrajyoti Datta Date: Mon, 4 May 2020 16:27:28 +0200 Subject: [PATCH] tty: xilinx_uartps: Fix missing id assignment to the console [ Upstream commit 2ae11c46d5fdc46cb396e35911c713d271056d35 ] When serial console has been assigned to ttyPS1 (which is serial1 alias) console index is not updated property and pointing to index -1 (statically initialized) which ends up in situation where nothing has been printed on the port. The commit 18cc7ac8a28e ("Revert "serial: uartps: Register own uart console and driver structures"") didn't contain this line which was removed by accident.
