X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=458ffce1cb46e46e3cec48b625ed142250475708;p=openwrt%2Fstaging%2Fblogic.git

media: cxd2880-spi: fix probe when dvb_attach fails

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")
