Subject: crypto: caam - dereferencing ERR_PTR on allocation failure
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cdc712d884cec0354d6899e7a329eee542ca2f7d;p=linux-beck.git

crypto: caam - dereferencing ERR_PTR on allocation failure

t_alg is an ERR_PTR here so we can't dereference it.
