Subject: [PATCH 6.1.y 2/3] staging: rtl8723bs: Fix space issues
Date: Tue, 14 Jul 2026 16:02:40 -0400	[thread overview]
Message-ID: <20260714200241.3154071-2-sashal@kernel.org> (raw)
In-Reply-To: <20260714200241.3154071-1-sashal@kernel.org>

From: Franziska Naepelt <franziska.naepelt@googlemail.com>

[ Upstream commit c4b811b9361b0d7ea167a79587f5ec0a13fd8863 ]

Fix the following checkpatch space issues:
- CHECK: spaces preferred around that '*' (ctx:VxV)
- CHECK: spaces preferred around that '+' (ctx:VxV)
- CHECK: spaces preferred around that '-' (ctx:VxV)
- CHECK: spaces preferred around that '|' (ctx:VxV)
- CHECK: No space is necessary after a cast
- WARNING: please, no spaces at the start of a line
