Yunfeng Ye	62a9d9fc7a	crypto: hisilicon - Fix return value check in hisi_zip_acompress() ... The return valude of add_comp_head() is int, but @head_size is size_t, which is a unsigned type. size_t head_size; ... if (head_size < 0) // it will never work return -ENOMEM Modify the type of @head_size to int, then change the type to size_t when invoke hisi_zip_create_req() as a parameter.

Zhou Wang	62c455ca85	crypto: hisilicon - add HiSilicon ZIP accelerator support ... The HiSilicon ZIP accelerator implements the zlib and gzip algorithm. It uses Hisilicon QM as the interface to the CPU. This patch provides PCIe driver to the accelerator and registers it to crypto acomp interface. It also uses sgl as data input/output interface.
