[PATCH][next] can: etas_es58x: Fix missing null check on netdev pointer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

There is an assignment to *netdev that is can potentially be null but the
null check is checking netdev and not *netdev as intended. Fix this by
adding in the missing * operator.

Addresses-Coverity: ("Dereference before null check")
Fixes: 8537257874e9 ("can: etas_es58x: add core support for ETAS ES58X CAN USB interfaces")
