crypto: hisilicon/zip - fix mismatch in get/set sgl_sge_nr
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 hisi_zip when get/set the variable sgl_sge_nr.
The type of sgl_sge_nr is u16, and get/set sgl_sge_nr by
param_get/set_int.
Replacing param_get/set_int to param_get/set_ushort can fix this bug.
Fixes: f081fda293ffb ("crypto: hisilicon - add sgl_sge_nr module param for zip")
