[Buildroot] [PATCH] busybox: fix interaction with version selection removal and lzo fix

Thomas Petazzoni thomas.petazzoni at free-electrons.com
Fri Jul 11 18:04:18 UTC 2014


The fix for the LZO issue in Busybox was merged between the moment the
patch removing the Busybox version selection was posted and
merged. This patch adjusts the Busybox patches to take into account
this issue: it removes the LZO patches for the no-longer existing
Busybox versions, and moves the LZO fix for the 1.22.1 Busybox version
as appropriate.
