+Subject: [PATCH 22/32] firmware: arm_ffa: Fix FFA_MEM_SHARE and
+ FFA_MEM_FRAG_TX
+
+FFA memory share on success might return FFA_MEM_FRAG_RX. In that case
+set handle from w1/w2 from FFA return value.
+
+FFA_MEM_FRAG_TX call will return FFA_SUCCESS for the last fragment, so
+check for this return code.
