Release name not correct when building kernel on Pi2 - Raspberry Pi Forums

i wanted add egalax usb touchscreen driver 7" screen , touch panel have.
followed steps updating gcc 4.8, , used rpi-source correct source github.

did 'make bcm2709_defconfig' , 'make menuconfig' ok
able build new kernel , modules 'make -j 6' , 'make -j 6 modules'

however, instead of producing 3.18.7-v7+ expected, building 3.18.7+-v7 isn't wanted; ideally want able update modules, not replace entire kernel.

so, 2 issues:

1. how can fix issue magic '+' appended after '-v7' suffix
2. how install newly compiled usbtouch module existing system 'minimum footprint', example, copying .ko file /lib/modules/3.18.7-v7+/kernel/drivers/input , running depmod?

while reasonably competent c/c++ programmer, it's been while since did kernel stuff, , hadn't expected run issue. there somewhere explains it?

seems wouldn't able #2, unless can resolve #1 first!

since '-v7' pi2 specific, right in thinking if did same build on pi1 (obviously correct default configuration!), problem wouldn't visible? ask since @ stage may want (although obviously, take lot longer...)


in advance.

well... have done 'sudo rpi-update' driver installed
