Commit 3885c2b463f6 ("MIPS: CM: Add support for reporting CM cache
errors") added cases for decoding errors reported by CM3, but leaves the
buf variable which is printed as a string uninitialised for cause values
other than 1, 2 or 3. Fix by ensuring the buf variable is initialised to
an empty string in such cases.Signed-off-by: Paul Burton <[email protected]> --- arch/mips/kernel/mips-cm.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/mips/kernel/mips-cm.c b/arch/mips/kernel/mips-cm.c index 10524ce..88a8e21 100644 --- a/arch/mips/kernel/mips-cm.c +++ b/arch/mips/kernel/mips-cm.c @@ -366,6 +366,8 @@ void mips_cm_error_report(void) cm3_cmd_group[cmd_group_bits], cm3_cca_bits, 1 << mcp_bits, cm3_tr[cm3_tr_bits], sched_bit); + } else { + buf[0] = 0; } pr_err("CM_ERROR=%llx %s <%s>\n", cm_error, -- 2.5.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
