mmc: rockchip_sdhci: Do not test unsigned for being less than 0
In rockchip_sdhci_execute_tuning the variable tuning_loop_counter is tested for being less than 0. Ensure that it is a signed type by declaring it as s8 instead of char. This issue was found by Smatch. Signed-off-by: Andrew Goodbody <andrew.goodbody@linaro.org> Reviewed-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
