Subject: power: supply: core: Break capacity loop
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=998d157e3b2acf5f605e49805f4c34947f3bad56;p=linux-block.git

power: supply: core: Break capacity loop

commit 51c7b6a0398f54b9120795796a4cff4fc9634f7d upstream.

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")
