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

[Lee Jones]

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 ‘fotg210_run’:
 drivers/usb/host/fotg210-hcd.c:5013:6: warning: variable ‘hcc_params’ set but not used [-Wunused-but-set-variable]
 5013 | u32 hcc_params;
 | ^~~~~~~~~~
