* gnu/packages/linux.scm (tlp)
[inputs]: Add system specific x86-energy-perf-policy dependency.
[arguments]<#:phases>['wrap]:
Adjust bin-directory procedure to return #f on missing input,
a guard against system specific input dependencies.
Filter only strings in the path list. Reformat for-each block.
Add x86-energy-perf-policy in bin-directory input-name list.
