KASAN reported this Bug:

[17619.659757] BUG: KASAN: global-out-of-bounds in param_get_int+0x34/0x60
[17619.673193] Read of size 4 at addr fffff01332d7ed00 by task read_all/1507958
...
[17619.698934] The buggy address belongs to the variable:
[17619.708371]  sgl_sge_nr+0x0/0xffffffffffffa300 [hisi_zip]

There is a mismatch in hisizip when get/set the variable sglsgenr. The type of sglsgenr is u16, and get/set sglsgenr by paramget/set_int.

Replacing paramget/setint to paramget/setushort can fix this bug.
