[PATCH 5.19 0354/1157] crypto: sun8i-ss - fix a NULL vs IS_ERR() check in sun8i_ss_hashkey

[Greg Kroah-Hartman]

From: Peng Wu <wupeng58@xxxxxxxxxx>

[ Upstream commit 7e8df1fc2d669d04c1f8a9e2d61d7afba1b43df4 ]

The crypto_alloc_shash() function never returns NULL. It returns error
pointers.

Fixes: 801b7d572c0a ("crypto: sun8i-ss - add hmac(sha1)")
