Interesting comment ;)

Unfortunately I get this error unless I remove the __init:
...
GEN .version
CHK include/generated/compile.h
AR built-in.a
LD vmlinux.o
MODPOST vmlinux.o
WARNING: vmlinux.o(.data+0x14e48): Section mismatch in reference from
the variable .LANCHOR0 to the function
.init.text:sifive_serial_console_setup()
The variable .LANCHOR0 references
the function __init sifive_serial_console_setup()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
FATAL: modpost: Section mismatches detected.
Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.
make[1]: *** [scripts/Makefile.modpost:98: vmlinux.o] Error 1
make: *** [Makefile:1040: vmlinux] Error 2
I have
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_SERIAL_SIFIVE=y
CONFIG_SERIAL_SIFIVE_CONSOLE=y
and it happens both on v4.20-rc2 and v4.19.
Without the __init everything seems to work fine though.

Missing "inline"?

If you're sending a v4 anyway, here and in the the probe function
using int ret; for this kind of variable is a common idiom and
hence easier to read.
