lgdt330x: fix signedness error in i2c_read_demod_bytes()
commit 34817174fca0c5512c2d5b6ea0fc37a0337ce1d8 upstream.
The error handling in lgdt3303_read_status() and lgdt330x_read_ucblocks()
doesn't work, because i2c_read_demod_bytes() returns a u8 and (err < 0)
is always false.
err = i2c_read_demod_bytes(state, 0x58, buf, 1);
if (err < 0)
return err;
Change the return type of i2c_read_demod_bytes() to int. Also change
the return value on error to -EIO to make (err < 0) work.
