Subject: crypto: hisilicon - update mininum queue
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c4f8f62fe13ae397fb7339d31eaee5fbe81f4560;p=linux.git

crypto: hisilicon - update mininum queue

At present, as HPRE/SEC/ZIP modules' parameter 'pf_q_num' is 1,
kernel CRYPTO test will fail on the algorithms from the modules,
since 'QP' hardware resources are not enough for CRYPTO TFM.
To fix this, the minimum value of 'pf_q_num' should be 2.
