Subject: [PATCH][next] media: cxd2880-spi: Fix a null pointer dereference on error handling path
Date: Tue, 20 Jul 2021 17:07:49 +0100	[thread overview]
Message-ID: <> (raw)

From: Colin Ian King <>

Currently the null pointer check on dvb_spi->vcc_supply is inverted and
this leads to only null values of the dvb_spi->vcc_supply being passed
to the call of regulator_disable causing null pointer dereferences.
Fix this by only calling regulator_disable if dvb_spi->vcc_supply is
not null.

Addresses-Coverity: ("Dereference after null check")
Fixes: dcb014582101 ("media: cxd2880-spi: Fix an error handling path")
