Subject: [PATCH 5.10/5.15 1/2] power: supply: Fix typo in power_supply_check_supplies
Date: Mon,  2 Nov 2026 14:12:31 +0300	[thread overview]
Message-ID: <20261102111233.383-2-mdmitrichenko@astralinux.ru> (raw)
In-Reply-To: <20261102111233.383-1-mdmitrichenko@astralinux.ru>

From: Schspa Shi <schspa@gmail.com>

commit 966f6551173ac46183db6621451702a7e4a3d4b5 upstream.

It seems to be a typo, there is no actual BUG, but it's better to
fix it to avoid any possible BUG after we change the type of
supplied_from.
