Subject: [PATCH] i2c: core: check returned size of emulated smbus block read

If the i2c bus driver ignores the I2C_M_RECV_LEN flag (as some of
them do), it is possible for an I2C_SMBUS_BLOCK_DATA read issued
on some random device to return an arbitrary value in the first
byte (and nothing else).  When this happens, i2c_smbus_xfer_emulated()
will happily write past the end of the supplied data buffer, thus
