[PATCH 5.10/5.15 1/2] power: supply: Fix typo in power_supply_check_supplies

[Mikhail Dmitrichenko]

From: Schspa Shi <schspa@xxxxxxxxx>

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.
