In several dbtr functions, we first check that the dbtr trigger is not NULL and that its state is what we expect. However, it only makes sense to perform the second check if the dbtr trigger is not NULL. Othwerwise we will dereference a NULL pointer. Thus, change the condition so that it shortcuts to the first check if necessary. Signed-off-by: Carlos López <carlos.lopezr4096@gmail.com> Reviewed-By: Anup Patel <anup@brainfault.org>
