Jeffrey Hugo a2cbb1a45a bus: mhi: host: Range check CHDBOFF and ERDBOFF 
commit 6a0c637bfee69a74c104468544d9f2a6579626d0 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.

Fixes: 6cd330ae76ff ("bus: mhi: core: Add support for ringing channel/event ring doorbells")
