Shuah Khan 1ad77b5c29 [media] drx-j: fix boot failure due to null pointer dereference
DJH_DEBUG only code path in drxbsp_i2c_write_read() dereferences
w_dev_addr and subsequently w_dev_addr->user_data->i2c which results
in failure during boot. This patch fixes the null pointer derefence
bug as well as the following compile errors:
