[PATCH 18/32] usb: host: fotg210-hcd: Remove unused variable 'hcc_params'

From: Lee Jones
Date: Mon Jul 06 2020 - 09:35:34 EST


The result is actually read into fotg210->caps->hcc_params. No
need to popuate an unused varible with the unchecked return value
from fotg210_readl().

Fixes the following W=1 kernel build warning(s):

drivers/usb/host/fotg210-hcd.c: In function âfotg210_runâ:
drivers/usb/host/fotg210-hcd.c:5013:6: warning: variable âhcc_paramsâ set but not used [-Wunused-but-set-variable]
5013 | u32 hcc_params;
| ^~~~~~~~~~
