Subject: media: cx18: check for allocation failure in cx18_read_eeprom()
From: Dan Carpenter <[email protected]>
commit e351bf25fa373a3de0be2141b962c5c3c27006a2 upstream.
It upsets static checkers when we don't check for allocation failure. I
moved the memset() of "tv" earlier so we don't use uninitialized data on
error.
