Subject: [PATCH 37/37] beaglebone: compare complete partnumber, not the first 5 chars when detecting capes
Otherwise it will init multiple capes when only one is present:
[ 0.456913] BeagleBone cape EEPROM: found eeprom at address 0x56
[ 0.456932] BeagleBone cape: Beagleboardtoys BeagleBone DVI-D CAPE
[ 0.456948] BeagleBone cape partnumber: BB-BONE-DVID-01
[ 0.456961] BeagleBone cape: initializing DVI cape
[ 0.492772] BeagleBone cape: initializing LCD cape
