EDAC, octeon: Fix an uninitialized variable warning
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.
