Subject: [PATCH] usb: isp1760: fix memory pool initialization
Git-commit: f757f9291f920e1da4c6cfd4064c6bf59639983e
Patch-mainline: v5.15-rc1
References: stable-5.14.6

[ Upstream commit f757f9291f920e1da4c6cfd4064c6bf59639983e ]

The loops to setup the memory pool were skipping some
blocks, that was not visible on the ISP1763 because it has
fewer blocks than the ISP1761. But won testing on that IP
from the family that would be an issue.
