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.

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.
