From: Arnd Bergmann <arnd@xxxxxxxx>
The dvb_register_device() function can return an uninitialized
error code:
drivers/media/dvb-core/dvbdev.c:554:10: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized]
554 | return ret;
| ^~~
Change this to -EINVAL as in the other half of the #ifdef block.
Fixes: 972e63e895ab ("media: dvbdev: prevent the risk of out of memory access")
