some scripts for configuring a kernel:

To translate a module name (as listed in modprobe -l or modinfo -n module) into a kernel .config option:

   #!/bin/bash
   mod="${1%.ko}";
   dir="${1%/*}";
   sed -e :a -e '/\\$/N; s/\\\n//; ta' "${dir#*/kernel/}/Makefile" | \
   sed -n "s/^obj-\$(CONFIG_\([A-Z0-9_]*\))\W*+=\W*"${mod##*/}"\.o$/\1/p";

a stupid sed script to check ioremap/iounmap balancing (can be adapted for others)

   git-grep -l '[^A-Za-z0-9]ioremap' | while read g; do
   echo "--------------------------[ $g ]--------------------------"
   sed -n "/[^A-Za-z0-9]ioremap.*(\(.*\))/,/^[}{]$/{
   s/\(.*return.*\)/\1\t\t-------return/
   tp
   s/\(.*goto.*\)/\1\t\t------goto/
   tp
   s/\(.*iounmap.*\)/\1\t\t<----/
   tp
   s/\(.*ioremap.*\)/\1\t\t---->/
   Tp
   =
   :p
   p
   }" $g
   done | less
