Subject: [PATCH] power: supply: core: Break capacity loop
Git-commit: 51c7b6a0398f54b9120795796a4cff4fc9634f7d
Patch-mainline: v5.16
References: git-fixes

We should not go on looking for more capacity tables after
we realize we have looked at the last one in
power_supply_find_ocv2cap_table().

Fixes: 3afb50d7125b ("power: supply: core: Add some helpers to use the battery OCV capacity table")
