Subject: [PATCH next] ACPICA: AML Parser: Remove spurious precision from format used to dump parse trees
Date: Thu, 26 Mar 2026 20:18:30 +0000	[thread overview]
Message-ID: <20260326201830.3938-1-david.laight.linux@gmail.com> (raw)

From: David Laight <david.laight.linux@gmail.com>

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.
