kumquat-buildroot/package/libsrtp/0001-Rename-SHA1-functions-to-avoid-conflicts-with-downst.patch
Vicente Olivert Riera 08b7e4e534 libsrtp: fix SHA1 functions conflicts with downstream packages 
Our current version of libsrtp is preventing linphone to build causing
an error like this one:

configure:12952: error: This libsrtp version exports symbols conflicting
with other libraries. Please use the one from
git://git.linphone.org/srtp.git

Backporting an upstream patch to rename the SHA1 functions to avoid
conflicts with downstream packages:

  c270245a94

Fixes:
