[PATCH 0/2] Bootlogd eating output without console= on cmdline

[Alexander Vickberg]

Hello list,

Bootlogd is eating the log data and doesn't forward it to console. The issue
arised with commit 986bee6. The log is correctly written to the file. My system
does not specify console as boot argument but instead uses 'stdout-path' in the
device-tree, e.g:

chosen {
        bootargs = "earlycon uio_pdrv_genirq.of_id=generic-uio ubi.mtd=ubi";
        stdout-path = "serial0:115200n8";
};

With this configuration bootlogd fails to detect current console. I have made
a patch to fix it by bringing back removed code which checks either which tty
is 'stdin' or using TIOCGDEV ioctl on 'stdin'. Both worked on my system (Linux
5.10). Patches are proposals and have not been tested on any other system than
Linux.

Best regards
Alexander Vickberg
