busybox: remove CVE-2014-9645 patch (already upstream in 1.23.x)
PATCH 1/1 busybox: remove CVE-2014-9645 patch (already upstream in 1.23.x)
The CVE-2014-9645 fix was merged in Busybox prior to the 1.23.0 release [1]. The fix was then reworked in Busybox 1.23.1, in such a way that the original change was no longer required [2].
Although oe-core's CVE-2014-9645 patch still applies cleanly to Busybox 1.23.1 and 1.23.2, applying it partially reverts the second version of the upstream fix.
