commit 544e92581a2ac44607d7cc602c6b54d18656f56d upstream.

Fix an uninitialized variable warning in the Octeon EDAC driver, as seen in MIPS cavium_octeon_defconfig builds since v4.14 with Codescape GNU Tools 2016.05-03:

drivers/edac/octeon_edac-lmc.c In function ‘octeon_lmc_edac_poll_o2’:

  drivers/edac/octeon_edac-lmc.c:87:24: warning: ‘((long unsigned int*)&int_reg)[1]’ may \
    be used uninitialized in this function [-Wmaybe-uninitialized]
    if (int_reg.s.sec_err || int_reg.s.ded_err) {
                        ^

Iinitialise the whole int_reg variable to zero before the conditional assignments in the error injection case.
