Subject: drivers/media/dvb-frontends/mb86a20s.c:706 mb86a20s_attach() error: potential null dereference 'state'. (kzalloc returns null)

commit: f66d81b54dac26d4e601d4d7faca53f3bdc98427 [media] mb86a20s: convert it to use dev_info/dev_err/dev_dbg
drivers/media/dvb-frontends/mb86a20s.c:706 mb86a20s_attach() error: potential null dereference 'state'. (kzalloc returns null)
drivers/media/dvb-frontends/mb86a20s.c:706 mb86a20s_attach() error: we previously assumed 'state' could be null (see line 705)
As, at mb86a20s_attach(), we have an i2c pointer, use it for all printk
messages there, instead of state->i2c.
