V4L/DVB (7922): tuner-simple: fix tuner_warn() induced kernel oops in simple_tuner_attach()
The tuner_warn() macro relies on the local variable "priv" to be a valid
pointer. There was a case in simple_tuner_attach() where this cannot be the
case yet, so tuner_warn() would dereference a NULL "priv" pointer. Changed
the tuner_warn() to a printk() with the originally intended output format.
