Resize signature buffer

Browse Source

There is an ambiguity in the use of the signature length in
OEMCrypto_GenerateRSASignature.  If the pointer to the vector is null,
the function should set the length parameter to be the size of the
buffer needed.

This ambiguity has been clarified in the documentation: the
length returned should be the exact length of the buffer.  It
will be corrected in a future release of Qualcomm's L1.  However,
we are putting this change in both as a stop-gap and as a
belt-and-suspenders fix.
