From: Lee Jones Date: Mon, 6 Jul 2020 13:33:27 +0000 (+0100) Subject: usb: host: fotg210-hcd: Remove unused variable 'hcc_params' X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=522514e599e3ceb9a34bcdd919db58e243a50cb2;p=linux.git usb: host: fotg210-hcd: Remove unused variable 'hcc_params' 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().
