Subject: [PATCH 1/2] media: cxd2880-spi: Fix an error handling path
Date: Fri, 21 May 2021 14:18:14 +0200	[thread overview]
Message-ID: <28a115d7207b258715a029f822ab88f7a4ee05e6.1621599392.git.christophe.jaillet@wanadoo.fr> (raw)

If an error occurs after a successful 'regulator_enable()' call,
'regulator_disable()' must be called.

Fix the error handling path of the probe accordingly.

Fixes: cb496cd472af ("media: cxd2880-spi: Add optional vcc regulator")
