crypto: rsa - add a check for allocation failure

Browse source

[ Upstream commit d872ca165c ]

Static checkers insist that the mpi_alloc() allocation can fail so add
a check to prevent a NULL dereference.  Small allocations like this
can't actually fail in current kernels, but adding a check is very
simple and makes the static checkers happy.
