Subject: crypto: caam - fix invalid dereference in caam_rsa_init_tfm()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit 33fa46d7b310e06d2cb2ab5417c100af120bfb65 upstream.

In case caam_jr_alloc() fails, ctx->dev carries the error code,
thus accessing it with dev_err() is incorrect.

Fixes: 8c419778ab57e ("crypto: caam - add support for RSA algorithm")
