[ Upstream commit 38aa192a05f22f9778f9420e630f0322525ef12e ]
The ecc.c file started out as part of the ECDH algorithm but got
moved out into a standalone module later. It does not build without
CRYPTO_DEFAULT_RNG, so now that other modules are using it as well we
can run into this link error:
aarch64-linux-ld: ecc.c:(.text+0xfc8): undefined reference to `crypto_default_rng'
aarch64-linux-ld: ecc.c:(.text+0xff4): undefined reference to `crypto_put_default_rng'
Move the 'select CRYPTO_DEFAULT_RNG' statement into the correct symbol.
Fixes: 0d7a78643f69 ("crypto: ecrdsa - add EC-RDSA (GOST 34.10) algorithm")
Fixes: 4e6602916bc6 ("crypto: ecdsa - Add support for ECDSA signature verification")
