[PATCH 4.19 165/243] media: cxd2880-spi: fix probe when dvb_attach fails
From: Greg Kroah-Hartman
Date: Wed Dec 11 2019 - 10:23:56 EST
From: Neil Armstrong <narmstrong@xxxxxxxxxxxx>
[ Upstream commit 458ffce1cb46e46e3cec48b625ed142250475708 ]
When dvb_attach fails, probe returns 0, and remove crashes afterwards.
This patch sets the return value to -ENODEV when attach fails.
Fixes: bd24fcddf6b8 ("media: cxd2880-spi: Add support for CXD2880 SPI interface")
