Jeffrey Hugo a2cbb1a45a bus: mhi: host: Range check CHDBOFF and ERDBOFF ... commit 6a0c637bfe upstream. If the value read from the CHDBOFF and ERDBOFF registers is outside the range of the MHI register space then an invalid address might be computed which later causes a kernel panic. Range check the read value to prevent a crash due to bad data from the device.
