# Prerequisites:
# - If called from DKMS, e.g. in the POST_INSTALL, someone (mainly Makefile)
#   should save DKMS KERNELRELEASE value to file `crono_dkms_kver`, so the 
#   script reads it and passes it to `install.sh`. 
#

# Get pwd, supposed to be /var/lib/dkms/crono_pci_drvmod/<version>/source

# `crono_dkms_kver` should have been created using our Makefile, 
# on /var/lib/dkms/crono_pci_drvmod/<version>/ with the DKMS kernel version.
cd ..
