Subject: [PATCH net-next] net: phy: at803x: Use devm_regulator_get_enable_optional()
Date: Sat, 17 Jun 2023 16:24:37 +0200 [thread overview]
Message-ID: <f5fdf1a50bb164b4f59409d3a70a2689515d59c9.1687011839.git.christophe.jaillet@wanadoo.fr> (raw)
Use devm_regulator_get_enable_optional() instead of hand writing it. It
saves some line of code.
Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
---
Compile tested-only.
If my reading is correct, regulator_disable() is still called in the same
order, should an error occur or the driver be removed.
