+Subject: i2c/designware: Fix an initialization issue
+
+From: Michael J. Ruhl <michael.j.ruhl@intel.com>
+
+commit 3d30048958e0d43425f6d4e76565e6249fa71050 upstream.
+
+The i2c_dw_xfer_init() function requires msgs and msg_write_idx from the
+dev context to be initialized.
+
+amd_i2c_dw_xfer_quirk() inits msgs and msgs_num, but not msg_write_idx.
+
+This could allow an out of bounds access (of msgs).
+
+Initialize msg_write_idx before calling i2c_dw_xfer_init().
