HID: cp2112: fix incorrect error propagation in cp2112_xfer()
Both cp2112_read_req() and cp2112_write_req() are returning negative value in cases of error, but cp2112_xfer() is storing the return value into unsigned size_t-typed 'count'. Fix this by making 'count' signed type. Reported-by: fengguang.wu@intel.com Signed-off-by: Jiri Kosina <jkosina@suse.cz>
