clocksource: acpi_pm: fix return value of __setup handler
[ Upstream commit 6a861abceecb68497dd82a324fee45a5332dcece ]
__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) environment strings.
The __setup() handler interface isn't meant to handle negative return
values -- they are non-zero, so they mean "handled" (like a return
value of 1 does), but that's just a quirk. So return 1 from
parse_pmtmr(). Also print a warning message if kstrtouint() returns
an error.
Fixes: 6b148507d3d0 ("pmtmr: allow command line override of ioport")
