Subject: [kvm-unit-tests PATCH v5 03/29] lib: Apply Lindent to acpi.{c,h}
Date: Fri, 28 Apr 2023 13:03:39 +0100 [thread overview]
Message-ID: <20230428120405.3770496-4-nikos.nikoleris@arm.com> (raw)
In-Reply-To: <20230428120405.3770496-1-nikos.nikoleris@arm.com>
The change was done by modifying Linux's scripts/Lindent to use 100
columns instead of 80.
