Subject: [PATCH 08/23] selftests/nolibc: Rename w to written in expect_vfprintf()
Date: Mon,  2 Mar 2026 10:18:00 +0000	[thread overview]
Message-ID: <20260302101815.3043-9-david.laight.linux@gmail.com> (raw)
In-Reply-To: <20260302101815.3043-1-david.laight.linux@gmail.com>

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

Single character variable names don't make code easy to read.
Rename 'w' (used for the return value from snprintf()) 'written'.

Signed-off-by: David Laight <david.laight.linux@gmail.com>

V4: Split out from patch 4.
