[PATCH v1 23/27] ACPICA: Remove spurious precision from format used to dump parse trees

From: Rafael J. Wysocki

Date: Wed May 27 2026 - 14:16:46 EST


From: David Laight <david.laight.linux@xxxxxxxxx>

The debug code in acpi_ps_delete_parse_tree() uses ("%*.s", level * 4, " ")
to indent traces.

POSIX requires the empty precision be treated as zero, but the kernel treats
is as 'no precision specified'.

Change to ("%*s", level * 4, "") since there is additional whitespace and no
reason to indent by one space when level is zero.
