Subject: [PATCH] power: supply: cw2015: use dev_err_probe to allow deferred probe
Git-commit: ad1abe476995d97bfe7546ea91bb4f3dcdfbf3ab
Patch-mainline: v5.15-rc1
References: git-fixes stable-5.14.4
Deal with deferred probe using dev_err_probe so the error is handled
and avoid logging lots probe defer information like the following:
[ 9.125121] cw2015 4-0062: Failed to register power supply
[ 9.211131] cw2015 4-0062: Failed to register power supply
Fixes: b4c7715c10c1 ("power: supply: add CellWise cw2015 fuel gauge driver")
