Subject: [media] media: fix au0828_analog_register() to not free au0828_dev
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7559d13ccf9fc4be9fb6ed21aaa4e105b6789ce8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[media] media: fix au0828_analog_register() to not free au0828_dev

au0828_analog_register() frees au0828_dev when it fails to
locate isoc endpoint. au0828_usb_probe() continues with dvb
and rc probe and registration assuming dev is still valid.
When au0828_analog_register() fails to locate isoc endpoint,
it should return without free'ing au0828_dev. Otherwise, the
probe will fail as dev is null when au0828_dvb_register() is
called.
