[PATCH 2/2] soc: qcom: cmd-db: Fix compiler warnings

[Andy Gross <andy.gross@linaro.org>]

This patch adds initialization of the entry_header structs to avoid
compiler warnings like the following:

  CC      drivers/soc/qcom/cmd-db.o
drivers/soc/qcom/cmd-db.c: In function ‘cmd_db_read_addr’:
drivers/soc/qcom/cmd-db.c:194:21: warning: ‘ent.addr’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
  return ret < 0 ? 0 : le32_to_cpu(ent.addr);

drivers/soc/qcom/cmd-db.c: In function ‘cmd_db_read_aux_data_len’:
drivers/soc/qcom/cmd-db.c:247:38: warning: ‘ent.len’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
  return ret < 0 ? 0 : le16_to_cpu(ent.len);
                                      ^

drivers/soc/qcom/cmd-db.c: In function ‘cmd_db_read_slave_id’:

drivers/soc/qcom/cmd-db.c:221:10: warning: ‘ent.len’ may be used

  ent_len = le16_to_cpu(ent.len);

drivers/soc/qcom/cmd-db.c:226:15: warning: ‘*((void *)&rsc_hdr+4)’ may
be used uninitialized in this function [-Wmaybe-uninitialized]
  memcpy(data, rsc_offset(&rsc_hdr, &ent), len);
               ^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/soc/qcom/cmd-db.c:226:15: warning: ‘*((void *)&ent+22)’ may be
used uninitialized in this function [-Wmaybe-uninitialized]
